A word used to say an old classmate had intercourse with a former teacher. It's origin is from the word "Pamphlet" in the sense that the teacher is the pamphlet, and is filled with knowledge, and the classmate "picked up" the pamphlet. The re-arranged letters makes it sound dirtier though.
Student 1: "Hey, you know how I said I saw our old teacher in the bar last night?"
Student 2: "Yeah, why?"
Student 1: "Well, Phamplet"
Student 1: "No way! High-Five!"
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.

Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.

Man, I just watched the funniest nutshot video ever.
