Hamburger
A handjob that is most commonly given by a student to their teacher or professor for brownie points. It is slightly less effective than a "cheeseburger" in achieving brownie points and is often referred to as a "handburger" as well.
Kat: Did you hear about how Garrett got an A+ on Dr. Cheekers's last biology quiz? Everyone else basically failed!

Alex: Dude... I bet he gave Dr. Cheekers a hamburger of epic proportions. Extra mayonnaise.
