The phenomenon of defecating and masturbating simultaneously. When performing a hand job it is vital to ejaculate semen precisely at the same moment as you poop. Although originated at Krym Peninsula (Ukraine), Krymka has been recently very popular in Krakow (Malopolska).
Optionally Krymka Mega is when you come directly on your own face and scream to yourself 'Who's the Boss! Ahhhh!'.
Last Monday, as soon as I woke up, I did Krymka before having Portugal breakfast and going to work.
