An entity with a slight resemblance to a ghost. Appears to be in the act of "wanking". Having only one arm, it's known to make the brave giggle and the weak cower in fear.
Dude, last night when I was walking home, I swear I saw a wankasaurus hiding in the woods! I was terrified!
complete jackass. whereas a wang is a guy who is moderately an asshole, a wanosaurus rex is a fucking idiot who is the very essense of being an asshole. yes, it is resonable to call the guy "the very essense of being an asshole" there is craft involved with opting instead to call him a wangosaurus rex.
"oh shit, that one dude who keeps wrecking open mic night by doing my chemical romance covers is here.... that dude is a total wang"
"shit, last week he tried to do a fall out boy cover..... on accoustic."
