A shreeker: a male, just impaled by another male's swollen and hard penis, let's out a scream or cry, like "EEEyahoooo...YIKKKKKKES" and usually follows the withdrawl of the penis with a gigantic and violent fart.
"I knew he was load as I'd fucked him before but DAMN, MAN, he's a shreeker...and WOW what a smell from the finale!!"
