i had a really shitty teacher in high school that never explained how to do the work so we had to either get someone else's paper and copy it or steal someone else paper and copy it...well he made us do our work on the computer one time and my buddy shared a locker with a smart kid that was in our class and your suppose to save your work as your intitials and his initials were DA...so he ended up gettin a computer next to us and he was talkin to us the whole time were using his disk and he finally looked at the computer and he's all DA? whats that stand for?....we were trying not to laugh and my buddy goes Dirt Ass and than he looked at me and goes no really whats it stand for?!... and i was like Dumb Ass?.....than he was like hey i'm DA! you assh*les! than he stole his disk back
