Popular girl: Sorry I'm late.
Teacher: Why are you late!
Girl: I need my beauty sleep.
Nerd: Well, you might need to hibernate because you ain't pretty.
Alright, listen up, buttercup. The "popular girl" waltzes in late, blaming it on needing her "beauty sleep". The nerd, bless his pointy little head, fires back that she's so ugly she needs to hibernate, like a bear in winter, to even have a chance at becoming attractive. Basically, he is implying that she's busted and needs a long time to fix it. And you, my friend, probably need a GPS to find your own butt.
