Another word for the male genitalia, penis, cock, or shlong. Refereeing specifically to the penis when fully erect. The phrase comes from the word “mirth”, meaning happiness, joy or pleasure, when also combined with “rocket”. Mirth rocket directly translates to “pleasure rocket” which can be interpreted as a slang word for the erect penis.

A means of delivering a baby via a hefty stomp on the stomach. This results in the infant being propelled from the womb, much resembling a bloody rocket.

When the pressure in your asshole reaches critical levels that no man can contain, an explosive bowel movement of gargantuan proportions jetisons all material underneath "the rocket", displacing the water in the bowl, creating a geyser of fecal matter. Best used when toilet is clogged.
The appropriate warning for such a manuvuer is to yell "Fire in the Hole!" as loud as possible to save anyone in a 50 foot radius.

When you have a tampon in and you’re doing an activity that requires intense physical exertion of the body, specifically from the abdomen and/or legs, that makes it feel like your tampon is going to shoot out like a rocket.
Dude I can’t go to the gym today, I’m gonna totally blow out a tamp rocket.
“Bro, Stacy blew out a colossal tamp rocket during her swim meet last night.”
“What was she doing?”
“The breaststroke.”
“Damn.”
