When during sexual intercourse and the male or female is about to ejaculate, he/she checks the other (in hockey terms) with a punch or other violent move as he/she has the orgasm.

Often ends relationships.
Well, we were having sex and I presumed to Echeckulate her, making her nose bleed. So she just left.

Get the Echeckulate mug.
When a waiter/waitress brings the check to your table even though you are in the middle of eating your meal and enjoying your drinks.
Wayne, "Is that the check for our meal? I'm still eating my steak and I want to order another drink."

Julie, "Yeah, it is another case of premature echeckulation."
