A person that try’s so hard at a video game that he/she ends up sweating.
That boy is so sweaty he just tryharded so much I bet he’s got sweat stains.
Sweaty is also used to describe a person who is gaming so intensely that they have neglected to shower, shaved, changed their clothes and/or remove the pizza boxes or food surrounding their PC/computer/laptop. You can game intensely and NOT be sweaty, however, often times intense gaming and being sweaty go hand in hand.
example
1) Them GRIZZLY boys (Classic WOW guild) are some sweaty bros.
2) "Baby, I'm about to start my sweaty grind to grand marshal"-man says to his wifey as she gasps in horror as her husband is covered in body hair, pizza stains, and is surround by coke cans used to spit his dip into.

A good time in New Orleans when the heats unavoidable.
Person 1: How was the warehouse party last night?
Person 2: Dude, so sweaty.
Person 1: Oh, so it was a really good time.
Anyone who likes any guitar based music. Anyone with long hair. Anyone with jeans, band t-shirt and a dark hoody. Sweaties could just have had a shower/bath and still they would be told to have a bath... basically chavs and crap just make shit up because theyre idiots.
A sweaty is walking down the street minding his/her own business when a chav approaches him.
"Oh yeah mate, fckng sweaty bstrd mate, want rumble do ya?"
"Uhh... wha?"
"Lamp ya out mate"
Whilst the lesser, weaker more annoying chavs say...
"Go on, lamp him out son. Needs a wash, needs a hair cut mate. Oh yeah!"
