When a guy attempts to talk to a girl whom he finds attractive but then totally blows it by stuttering or making sounds (usually loud) that more resemble animal noises than actual human speech. This often will frighten the pursued female, causing her to run for safety and will certainly become a source of ridicule for the "schoolboy" should any friends witness or find out about the event.
Drive-thru lady: Here are your milkshakes, guys.
Dan (driver): Thanks!
George (passenger): (whispering) Dan, say something nice to her to make her feel special.

Drive-thru lady: Those white boys are freaks.
George: Man, you really schoolboyed it there, Dan. I can't wait to tell everyone I know exactly what happened.
Dual Mungus is a serious fictional disease of the upper respiratory system. Dual Mungus is actually an advanced form of simple Mingus. Symptoms of Mingus are small spots and light wheezing. Mingus and Mungus are both a form of fungus. Full-blown Dual Mungus causes a debilitating cough that strikes fear and dread into the hearts of all who hear it. It is never certain how much time a victim of Dual Mungus has left on this mortal plane.
Patient: "Doctor, is it serious?"
Doctor: "I'm glad you're sitting down because I fear the worst. I suspect Dual Mungus. This situation is very grim."
Patient: "That's terrible! It wasn't this bad last week."
Doctor: "Sir! You had a mere case of Mingus last week. It has developed into full-blown Dual Mingus! This is grave indeed!"

Justin: <pukes>. Apparently. What an asshole.
