The color of an avetard's eyes after he takes a rip off the dab rig. This color also happens to be one of TardU's colors and it is no coincidence at all that an avetard will have the same color in his eyes. Whenever an avetard has this shade of red in his eyes, he is 100% out like a light.
Royal Navy slang dating back before the Second World War, it means to defecate, crap, shit or take a dump. Nothing fancy, to crimp off a length you merely have to evacuate your bowels.
"That fat fucker of a stoker is getting shitty with me again!"
"What're you goin' to do?"
"Next time the cunt is down the engine room, I'll crimp off a length in his best boots!"
