Young people who are still trying to decide which genre to represent, and they didn't cut it in the punk rock or metal scene, so they jumped on the rock-a-billy train. They like to think that because they own a coy of Grease, that they are in some sort of secret greaser club. They are usually identified by 3 to 4 inch-high pompadours, tatoos depicting tribal flames (which actually came about in the nineties), driving import cars or PT Cruisers (or bumming a ride in their girlfriend's Toyota or Hyundai.) They often wear their pant cuffs rolled up about 4 to 6 inches high, and sport excessively long chains on their wallets, so as to prevent theft of their wad of cash they earned at some fast-food joint. You can also spot them pulling their pack of smokes from their rolled up tee-shirt sleeve, and if they are out of smokes, may be seen htting up their pimply girlfriend for her last Virginia Slims (and a match). Then watch them as they pass a store window, stop and check their hairdo, then fix it with the greasy black comb they keep in their back pocket of their starched jeans. Frequently seen at psychobilly concerts or asking for an application at a Hot Topic store.

Get the mug
Get a rock-a-silly mug for your father-in-law Günter.
The beginning of this phrase started around the mid 90s, when some became more so aware of “Greasers” and “Rockabilly cats”, confused the two, and/or hated the two.

(1) A derogatory term or insult used for patriots of the rockabilly lifestyle.
(2) An insult expressing how one believes that Rockabilly is silly, for the style (referring to the Cats and Kittens whom are also 50s clothing enthusiasts), music, and attitude.
(3) One whom confuses a person involved in the rockabilly scene with one whom is a greaser that listens to Rockabilly music.
Jerk off #1: Look at this Rockasilly his pompadour, cuffed Levi’s, and lucky strikes!

Jerk off #2: Hey aren't you heard of that one band?
Pomped kid: To which band are you referring to?
Jerk off #2: Haahaa that stupid ROCKASILLY band that slaps around the stand up bass and sings about cars, booze, and pretty girls.
