sweet dude

Sweet dudes are guys who are over the top and don't realize it. Often they belong to frats. You can pick them out because they will be wearing polo shirts, often with popped collars, board shorts, flip-flops, and white baseball caps. They tend to demean women and can become paralized with fear when someone says something they did was "gay". Desperate for attention, they will often perform random acts of athleticism for no obvious reason. Basically, they are the guys from 'Dude, Where's My Car'.
It has become trendy within the sweet dude community to adopt a "punkish" style which can include anything from a Clash t-shirt to a short Mohawk, possibly dyed blue.

Other activities you might see a sweet dude engaged in:
Drinking Bud, Coors, or Miller lt.
Smoking pot
Listening to Dave Matthews and Jack Johnson
Tossing a football
Wearing gold chains
Getting tribal tattoos
Yelling, "Show us your tits!"

Ashton Kutcher is a sweet dude. Most of the guys who played football in highschool are sweet dudes. Almost every guy in Mexico on Spring Break is a sweet dude.

Look at this dude...

When you roast somebody about how they resemble a person or object to make them feel like dying.

"Look at this dude... he looking like a Duracell battery with that weak ass haircut."
