Acronym for Sweet dude, Sweet.

A saying after someone says something pointless.
Dude 1 tries to explain the usage of Under Armor.

Dude#1: Oh and fyi under armor is use to wick moisture away from the body which really enhances our body's temperature regulation ability. Making your body cool in hot weather and warm in cold weather, also when the body is active it keeps the muscles warmer so that you have less chances of pulling something.

Dude #2: K. SDS, man.
