One of Trumps many sycophantic white house staff, who get such a raging
boner from his position of
power they basically act like he can do no wrong and will defend his position at the cost of
everything; behaving like a simp only much worse, hence the term Sump.
Mitch McConnell: "Dude it's been almost 5 minutes and no-ones licked Trumps
asshole! Where the hell is Seb Gorka?"
Mike Pence: "Nah, he's
gone bro! Trump
fired him, he was way too much of a Sump!"
