When a penis is so small and wrinkly, and looks more like a cockroach than a cock.
"Is that a cock or a cockroach?" asked the girl when she saw his small, wrinkly dick.

Nasty little assholes that are everywhere. they never fucking die, until you smash the damn thing eighty times. and then their antenna thingers still move around you finally just get pissed off enough to get a napkin, pick it up and flush it down the toilet.

and they also make you squirm/scream like a mother fucker.

and i think you all know why they're nicknamed COCKroaches.
Angela:-walks into the bathroom; looks on the floor- AHHH, HOLY SHIT A COCKROACH! -jumps on the counter and chucks everything at it and it still doesn't die- GOD DAMMIT. SOMEONE HELP ME!!!

Marissa walks in the bathroom and sees the cockroach.

Marissa: "OH MY GOD, EW!" -smashes it with her shoe several times. " IT WON'T DIE!" -continues to smash it-

(n.) A pest-bug with an ability to rebound from danger, and famous for being a sign of a dirty house, and being able to withstand a nuclear war.

Similarly, it can refer to an annoying human who seems to be indestructable, yet annoying to those who don't have the ability to annoy themselves.
Dis man, he is a cock-a-roach.

A cockroach is a disgusting fucking insect that originally came from the deepest, darkest, slimiest, smelliest pits of hell.

They are an abomination!
If you end up seeing even one, JUST one, cockroach crawling around your house, then keep in mind that there are possibly hundreds more hiding inside cracks or walls.
