Words containing no vowels include Q.T. (as in "on the q.t."), DJ, and RX, which MWCD10 classifies as words rather than abbreviations. (The reason apparently is that the letters are pronounced. Thus RV is an abbreviation when it stands for Revised Version, but it is a word when it means recreational vehicle.) A plural of RX is RXS, which has no vowels but three pronounced syllables.
Other words having no vowels are BRRR, GRR, HMMMM, JHVH, MR., MRS., MS, NTH, PFFT, pH, PHPHT, PHT, PSST, SH, SHH, SSSHHHHH, TSK, TSKS, TSKTSK, TSKTSKS, TV, YHWH, ZZZ, HSH (hush, W3), ST (silence, quiet, W3), TCH (vexation or disgust, W3), TCK (surprise or displeasure), and TST (hissed sound enjoining silence, W3). PHFFFT! and SSSSSSS are titles of movies from 1954 and 1973. The OED has TPRW (the sound of a horn). GRRL is in the Macquarie Dictionary, with the alternate spelling GRRRL [Charles Turner].
This web page lists words having no vowels that are playable in Words with Friends. It lists some words with W used as a vowel.
Note: In some of the following entries, the consonants l and r function as sonorants and thus fulfill the role of a vowel.
KRK is a Croatian island [Juozas Rimas].
Richard VLK of Pittsburgh profited from a vowelless last name in 1983 when he won over $20,000 by finding enough flip tops from Pepsi cans to spell his name 1,393 times.
William P. MLKVY played basketball for Temple University. He is referred to as the "Owl Without a Vowel," although the Y in his name is a vowel.

The OED2 has TWYNDYLLYNG(S). And WPPWRMWSTE (in the OED) goes nine letters without an A, E, I, O, or U. Paul Wright found that the will of William Tyllcott of Nailstone, Leicestershire, on the 2nd of April 1547, has, “I bequethe to evry one of my god CHYLLDRYN apeyste £14....” GLYCYRRHIZIN (a constituent of licorice) goes eight letters without A, E, I, O, or U. GLYCYPHYLLIN and GLYCYPHYLLOS each goes 10 letters without AEIOU. GLYCYLGLYCYLGLYCYLGLYCINE goes 22 letters without AEIOU. (In all these words, "Y" is a vowel. Paul Wright contributed to this section.)

The Croatian word OPSKRBLjIVAČ (supplier) has 7 consecutive consonants [Vjekoslav Babic].
A Croatian dialect word mrklj (snot; booger) is standardized as mrkalj merely because the Croatian standard allows for the syllabic r, but not the syllabic lj. (The syllabic l is allowed rarely, in a few exceptions such as bicikl - bicycle.) [Bojan Kopitar]

Mark D. Lew writes, “If you allow that "r" is a consonant (which is debatable), then words beginning with four consonants are commonplace in Czech, as are words consisting entirely of consonants. (KRK, PRST, SMRK, SMRT, SRDCE). Words beginning with five consonants are not too rare either. ČTVRT means quarter, and Thursday is ČTVRTEK. There is a professional volleyball player named Bob CTVRTLIK. The same is true of Serbo-Croatian, to a lesser extent. (CRKVA=church, MRKVA=carrot, TRG=market, ŽRTVA=victim). The great king of medieval Bosnia was named TVRTKO. Polish also has many common words beginning with four consonants, and a few beginning with five, though most of these include digraphs (PSZCZOLA=bee).”

Robert G. Wirth writes, "In Ukrainian, beet soup is called BORSHCH. So I can say: 'In Minneapolis there are two good borshchs, at the Ukrainian Hall and at Kramarczuk's Sausage Company.' Trouble is, in gaining the extra H we sacrifice the T; but the plural still has six consonants."
In Welsh, Bydd y cyllyll yn y cwpwrdd wrth y bwrdd ("The knives will be in the cupboard by the table") does not use the vowels a, e, i, o, and u. In 2014 Paul Wright lengthened the sentence to Bydd y cyllyll gwyrdd tywyll yn y cwpwrdd wrth y bwrdd gwyrdd tywyll (“The dark green knives will be in the cupboard by the dark green table”). He further lengthened it to Bydd y cyllyll gwyrdd tywyll yn y cwpwrdd gwyrdd tywyll yn y stryd wrth y bwrdd gwyrdd tywyll (“The dark green knives will be in the dark green cupboard in the street by the dark green table”).

It means "a thing of masculine gender that will not be made by oneself anymore".
