if you're mean to your girlfriend in her dream / your gonna have a bad time
A SouthPark Bad Time meme post.
The ski instructor from South Park's "Asspen" episode (2002), warning Stan: "If you ski off course, then you're gonna have a bad time." He gives the same advice in the same flat voice to every kid, every time, no matter what they ask. It is, for the record, very good advice. The top line names an obviously bad idea, the bottom line is always "you're gonna have a bad time". "If you reply-all to the whole company" / "you're gonna have a bad time." "If you wear new shoes on a long walk" / "you're gonna have a bad time." "If you eat gas station sushi" / "you're gonna have a bad time." The joke is that none of it needed saying. Everyone knew. He says it anyway, because someone always does it anyway. **Why it caught on:** it's the perfect deadpan way to warn a friend about a mistake they're definitely going to make.
