Actin like she never seen a magnum before"

^^ thats off a song and i was wondering what magnum meant?

Answer 1

.44 Magnum used to be the biggest handgun ever made. I think the .5 Magnum is currently out which is bigger than the one depicted in Clint Eastwoods movie "Dirty Harry".

Answer 2

Magnum is a big handgun, bigger than a normal handgun. He's comparing his d**k to a magnum. Also the name of the condom designed for bigger penises.

Makes sense?

Answer 3

He is comparing his p***s to a large handgun.
