One who's repetitious bragging resembles a prehistoric beast's warcry. These folks aren't ones you would wish to spend long amounts of time with. You will spend the majority of your time with them figuring out who to get them to leave.
RRRRRAWR I got this new truck, a raise, and I slept with 6 women last night. Advanced bragasaurus's can also be referred as bragasaurus rex's.

Any one, particularly a dude trying to brag about himself to anyone who will listen about anything he feels is note worthy..... Often obnoxious, uber basic, small penis and lies about how much sex he has, money he makes, etc.... Often unpopular with the ladies and is a one date wonder ... But, is in such denial of his douchary he blames the chicks....
That guy is a total Bragasaurus Rex! He couldn't stop bragging about himself or his lame ass life if he tried.
