When you or a friend are getting chatted up by someone whether they are attractive or not and it makes you feel good about yourself, too the extent that everyone else are your peasants.
Sam: I heard Chris Brown replied to your tweet last night.
Tanisha: Yeah, I got so gassed!
A somewhat positive emotion as a direct result of something positive happening. The word is often used to tease a gassed, as an attempt to get them to reluctantly blush or show positive emotion.
Girl: Hey Caleb. You look good today.
Caleb: Thanks *starts blushing*
Friend: Aww Caleb, I can see it in your face. You're gassed because you got complimented.
Caleb: *Trying to hold back his positive emotions* Whatever man, go away *smirks*
