Input: Text: last night was fraternity bid night on campus, so all the different fraternities went around handing out bids and congratulating the pledges-to-be. we were out til about 1am, so i was pretty tired. afterwards, a few of us went to the on-campus mini-mart type thing to grab a drink. the cashier, a funny black girl that knows a ton of people around the campus, asked if were chosen to be in fraternities. the guy next to me told her that we were the ones who had done the choosing, and she said something like, "ohh okay, how does it feel to be in a position of power like that?" and i said, "man i'm just excited to have slaves in a few days." 

she got this horrified look on her face and everyone around me went quiet. i couldn't understand why, since it was a pretty common joke around campus (and i'd assume just about every campus) that pledges were like slaves. after a second or two, i said, "err...i mean..excited to have associate members?" technically my school doesn't have pledges, we have 'associate members,' so i thought that was why she looked so shocked. she just silently nodded, and after i left the store my friends starting railing on me for saying something so horrible, and then it hit me like a truck. i told a black person i was excited to have slaves.

TIFU by coming off as a total racist
