Music Teacher: Pianissimo, abbreviated as pp,
Students: *Giggles hysterically*
Music Teacher: You are aware that you all are going to get detention at free time, aren't you?
Student: Pp/pianissimo is basically soft penis, lol.
Derived from the italian suffix -issimo, meaning "extreme" or "remarkable" and the english root penis, penissimo means an extremely large or remarkable penis, one that is pleasing to the eye, and a woman.
