A spoken line by the Heavy in TF2. To achieve it, it is mostly used during a handgun taunt resulting in Pootis Pow!

Friendly Heavy/Hoovy : Pootispencer here!
A portmanteau of floof and puff, it's basically saying that you're so puffy you're really cute.
Oh my god that's so ploofy i don't even *dies from cuteness overload*
