freshman fluff 

The small and/or hard to see facial/armpit/body/other hair on a male freshman that is often a source of mockery for them. The facial hair consists of only a light moustache with nothing else, and is generally very hard to see. The armpit and bodily hair is often only mentioned/seen in lockers rooms when the freshman is on a jv/varsity sport, and will make him the butt of jokes for the remainder of the season.

One senior to another in the halls:
"Get a load of that freshman fluff over there, does that kid even shave?"

In the lockeroom after football practice, Joe(a senior) says to Larry (a freshman):
"That's some nice freshman fluff armpit hair you've got there"
