The Rocket Launch when you're about to cum and the girl flips onto her back and opens her mouth and while you're finishing sneezes rocketing you're cum onto your ballsack and headbutting your ass cheeks
I thought I'd try something new until I had to sneeze and ended up rocket launching him.
A password (usually auto-generated) that is complete nonsense. Example: *)36/Pn=p>(JOp5dcqtUo"@G
These passwords are ironically a good practice to use since a brute-force attack based on non-nonsense data is more likely to guess a password like "fuckrobot34" than "lG.j"UXhSHZ*|c>j|$oBfXr1"
The phrase comes from the assumption that a string of characters needed to launch a rocket would be very random as to protect the system from hijacking.
