phlegkwus 

The moment when a son is masturbating, his mother enters the room, and their eyes meet. Possibly the most awkward to say and to think about.

Guy 1: How the fuck do you spell "phlegkwus"?
Guy 2: I don't know, but I experienced it last night, and now I'm grounded. Doesn't she understand that it's just what all guys do?

Phlegucus 

Phlegm and mucus. You get phlegucus when you either have Strep Throat, A cold, or a Sinus Infection. Usually comes out in thick, acidic chunks when one coughs.

"Dude, My throat hurt really bad!"

"Really? Did you have some phlegucus stuck in it?"
