A mixed rush of feelings and emotions when the president appears on TV. Very similar to an orgasm, an Orbamagasm causes uncontrollable body twitching; not out of pleasure, but out of frustration.
EVAN: Did you watch the presidential address last night?

TYLER: Yeah dude, I had the biggest orbamagasm right in the middle of it.

EVAN: Yeah I can't believe this country was stupid enough to vote for him.
