There's this one whimpering-esque noise that the Scout makes in gmod videos that, for some reason, I can never seem to get enough of.
I can't really describe what it sounds like, but he does it twice near the beginning of this video. You'll know it when you hear it. youtube.com/watch?v=S-j0Ki7vFq4
Why is pootis such a fun word to say? There's something about it...

AUGH!

This, and pretty much any of the stock sound effects like shattering glass or that one cat.
Camden Russell
There's no proper name, it's just a relief sigh

the Spy's snorting is always funny to me I love the sound effects they use from going back and forth between close ups of faces I also love the rubberfruit 'fingers break in every direction' thing
