A tall, skinny, blonde Caucasian kid with a brain to rival Patrick Starr and Big dick energy to rival Dwayne Johnson. He spends too much time online and never goes outside. Generally nice when you meet him, but gradually becomes more and more of an ass as you get to know him.
Wow Jack this is the fourth time you’ve told me to “Kazoom off a A cliff with a bus full of special ed kids” in 45 minutes. It’s not funny anymore

Get the jackmug. To jerk your dick until you cum into a girls vagina because it is too loose and you are getting bored.
Oh man, Miley's pussy was so loose last night that I ended up spending the last 20 minutes Jacking In her.
