pre-erackulation 

Occurs during a game of beer pong, when the opposite teams calls for a "re-rack" of their cups clearly before they are ready for a "re-rack".

The drunk girls' team yelled out "re-rack" to their teammates during a game of beer pong when they had 9 cups still sitting on the table, showing they were suffering from a bad case of pre-erackulation!

Pre-ejaculation 

The act of "half cumming" in which a man can feel ejaculation coming on, and then, at the first twitch of his scrotum, can control and then stop the orgasm, thus creating stamina he didn't know he had!

Jack was in full control until his girlfriend started screaming for him to come which caused "pre-ejaculation", but, after much concentration about tennis, he was able to stop his scrotum from twitching, and instead of cumming, rode for another hour and 11 minutes!
