SDS = Storm Deprivation Syndrome.

A condition often afflicting a seasoned storm chaser who have become accustom to routine sightings of severe weather and then deprived of it for a period exceeding expectation. It often results in irritability, non-rational thoughts, and teenage like drama. It is most often found with tornado chasers but can be found in hurricane chasers and snow weenies. It is mostly found in the off seasons of the weather event, but also can be prolonged for years if said chaser is not actively chasing season after season.

Posting online, in forums, facebook, etc. is known to inflame the situation.

The only known cures are to resume chase storms or getting laid.

“Chill dude, you got SDS if you think the GFS at 240 hours out is reliable”

Or
“Stuck at the office looking at the streaming video is giving me severe SDS”.

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.
