class boner

When the penis decides to erect itself and making it impossible to hide, resulting in the male adjusting to his elastic waste band. Although this tactic works sometimes the class boner counters this maneuver by making it obvious to the entire class what you're doing.

Girl: "hat are you doing"
Boy: "Just getting my phone out."
Girl: "lift your shirt up then"
Boy: "No....Why O.O"
*Girl lifts shirt up*
Girl: "Look everyone, he has a tiny class boner"

Math Class Boner

You know what it is. The boner that happens the second the bell rings to end math class. I guess the linear functions get us all hot and bothered.

Teacher: Can you do problem 4?
Student: ....I have the math class boner.

HOLY SHIFT. CHECK OUT THE ASYMPTOTE ON THAT MOTHER FUNCTION.

Dat mass.

Boner in Gym Class

Saying men use to compare something extremely embarrassing, to. Derived from experience some male teenagers go threw in which they get an erection in a gym class that ends up being extremely noticeable because of the loose basketball shorts everyone must wear in gym class.

Steve, "Dude did you just fart in front of Lisa?"
Brad, "Yeah, it was more embarrassing then a boner in gym class!"
