SESing 

Spontaneous Erection Syndrome: Affecting usually young teenage males 12-15 years old in which they unfold an erection randomly for no apparent reason. Similar to females' "PMSing", this term can refer to the embarrassing occurrence of this event.

Jimmy: "Did you just see Ben get a boner? I think he wants to get it on with Mrs. Patterson!"

Gerald: "Nah bro, he's just SESing."

seeing red 

In bullfighting, the matador beckons the bull with a red cape, which agitates the bull, and it charges for the cape.

Seeing red refers to when someone becomes so angered that it controls them, enraging the person.
