look up anything, like your first name:
1. IOI
An Indicator of Interest. Jargon used by a PUA. When he is talking to a girl, she will IOI him with subtle things, a trained eye can pick these up easily.

After three IOIs it is possible to go in for the kiss
Examples of IOIs:
1. If she starts playing with her hair
2. If she laughs at things that are not funny (being giggly)
3. If she asks you her name
4. You squeaze her hand, she squeazes back.
2. IOI
I'm Over It
Yvette: Hey did you hear about Lisa going postal over a comment I left on fb?
Gloria: IOI...she's bat shit crazy and will never change...
3. ioi
an acronym for the words "I'm Over It". not to be confused with the term "lol". they may look alike, but soon enough everyone will be using ioi more.
That bitch just made out with my ex! Oh whatever, ioi. He was a bad kisser anyway.
