Input: Text: so this actually happened about a year ago, i was reminded of it by a askreddit thread regarding how women let a guy know she likes them.

so me and friends decided to go to a club we are all drinking and i am very much intoxicated at this point so we assume hitting the dance floor will be a good idea. the dance floor in this club is basically empty apart from groups of people huddled together. so me and my friends start "dancing"(and i use the term loosely) next to a group of very attractive girls. now one of the girls starts backing up to me and grinding against me, so in my head i think "wow this girl probably doesn't know i'm here and it would be creepy for me to stay here", so being the gentleman that i am i move back a bit to give her room. noticing that i've moved she looks back bewildered and i mutter like "sorry about that" and continue my shitty dancing with my friends. a couple of minutes later she moves back and starts again. at this point i'm thinking ".. fucking hell how much room does this girl need!" so i move back again and she follows this then happens a couple of times until eventually i get annoyed and say like "fine i'll move over there then!!" and walk to the other side of the club followed by angry and slightly confused looks from the hot girl and her friends.

my friends then advise that the girl was grinding me and trying to get me to grind back.. i have no fucking clue what grinding is but i imagine i would of enjoyed it if i wasn't so clueless.

TIFU: By ignoring an attractive girls obvious advances.
