When your mind and body becomes so overwhelmed with such ecstatic joy while delivering the father of the groom speech that you yell out at the end "I'm having a mental ejaculation of joy" and then drop the mic.
Aka Poe.
This wedding makes me so happy It's a mental ejaculation of joy
When someone jumps the gun during an attempt to synchronize cracking open cans of soda or beer... therefore ruining the massive head-turning "clack" sound you were all hoping to create.
question: "Dude! what happened there? We were going to crack-open on the count of 3"
response: "Sorry man... I've been having trouble with premature eclackulation lately"
To orgasm after the act of sex has been completed. The opposite of pre-mature ejaculation.
Jack failed to ejaculate during sex with Jill but successfully came afterward while eating a bowl of cereal in a phenomenon known as post mature ejaculation.
when a zach just puts "it" in just a lil bit and cums prematurely , thus resulting in Plan B
Khloe: Last nightZach just put it in a little bit and still came really early, I need to go grab some plan B
Chasette: Aw damn girl sounds like your man got a case of premature ezachulation :(
