A Gymbag surprise is when your mother sends you a care package filled with extra clothes, deodorant, and other supplies. Upon receiving the package, you realize that she sent the items to you in one of her bags. You think nothing of it until, you have emptied all of YOUR belongings out, but the bag is still heavy.... You open up the side pouch to find your mom left her dildo and lube in the bag and sent it to you!!!!!
Tom can never look at his mother the same after she hit him with a gym bag surprise!
Sam doesn't know how he can ever thank his mom for the gym bag surprise.

The act of ejaculating into your hand after direct intercourse from behind, and smearing it into your partners face without warning. A customary shout of "SURPRISE" should follow
Chris 1: "Man, my girlfriend is really pissing me off"
Chris 2: "You should tell her off!"
Chris 1: "I'll just give her a Surprise Bag"
Chris 3: "SURPRISE!!"
