Most importantly, is ideal for finally striking up a conversation with that cute girl you've been checking out on facebook. But just so we're clear, "This sucks, huh?" is best used during:

-Lectures-Bad parties-Football game blow-outs-Dining hall lunches

And should never be used during:

-Parties at her place-Her grandma's funeral-First dates-Sex
