A small brown stone (rock) that comes out of your penis during sex with people of the same sex, sometimes comes out in text message format or coated in pepto-bismol
"Ahhh what was that"
"oh nothing just a cock stone"

"Whats that pink boulder?"
"think its a cock stone with pepto-bismol on it, just ignore it"

Get the cock stone mug.
Situation where a female is totally infatuated with her boyfriend and even lame excuses, used by her boyfriend to explain cheating, work e.g. "I tripped and landed in her pussy", "I'm a proctologist sweety, thats just one of our newer techniques we use"
Her boyfriend was cheating on her but she's too cock stoned to realise it.
