Doing something you haven't really gottime for, usually before going out. Origins from comedy series 'Police Squad' where the teller completes his chores after being fatally shot.
Where the hell is Kelly? We've gotta go!
She's still in the bathroom squadding!
When five guys wearing sunglasses fuck a single girl, preferably one in a nurse outfit, all pull out and ejaculate onto her back at the same time, while shouting: "Squirtle Squirt!".
"Dude, we took this girl back to our hotel last night, and before you know it, we were squirtle squadding!"
During intercourse when a male both ejaculates and rips ass at the same time. Truly one of the best feelings of all time although it may lead to you being single.
Dude, last night I totally pulled the elusive squawking dragon with my girlfriend. She was less than impressed.
