The Person Who Pitches You Nonstop
You're trying to hear B.I.G. and some cuts from Nore, and they keep talking over the beat like Clue. This person can be a rapper, publicist, or struggling writer. Regardless of occupation, they're trying to sell you on something and they will be relentless about it. They'll whip out their phone and follow you on Twitter on the spot, and you'll pretend that you intend on following back sometime before the year ends.
Their enthusiasm is appreciated, but it'd be better suited for a more business appropriate setting. You're six whiskey gingers deep and really just waiting for the DJ to play "Love Sosa." If only they knew that relaxing and behaving like a normal person could actually lead to a real, beneficial relationship, then maybe they'd chill. Until they learn, just take the business card you didn't ask for and keep it moving.
