that special day of the year when girls (or usually just one girl and her friend) as an inside joke, dress as slutty as possible to make fun of all of those other bitches who do it daily, thinking they look so hot. *also to see how many guys get "excited" if you know what i mean ;]*
I'm wearing my mini skirt and thong on National Dress Like a Slut Day.
1. The French pronunciation of "giggle like a schoolgirl" due to the letter G being pronounced like the letter J;
2. To bounce in glee like an anime preteen;
3. Yann's catchphrase of the day.
"I told Erin she had nice hair and she replied that I made her blush and jiggle like a schoolgirl".
