Full Lobster

When someone's fury reaches such a level that they turn red and begin to produce hot sweat. If male, will occasionally get a fat, sweaty boner as well.

Dude, stop calling Tommy a testicle-shitting rectal wart..

Yeah, seriously, stop! This nigga's about to go full lobster!

Full Blown Lobsters

A bad case of crabs or a funny way to say someone has or could possibly have crabs.

'Dude, he doesn't have crabs, he has full blown lobsters!'
