you know you got it bad when you're stuck in the house, you don't wanna have fun, they're all you think about. You got it bad when you're out with someone but you keep on thinking bout somebody, you got it bad.Which, now that I type it out, doesn't make much grammatical sense at all.
Lesson of the day: never learn grammar from Usher. You'll fail English. Especially seeing as that should be "u got it bad."
