We had a guy when i was in high school, he was kinda nerdy, but he would kinda bother the popular girls [especially cheerleaders!] and he would walk up behind them and tickle them in the ribs, it was pretty good, one time he tickled a hot looking cheerleader who was extremly ticklish and when he tickled her in the ribs she screamed loud jumped and embarassed looking said 'don't do that' it was great and he tickled her several times one day and would run away and she thought that it was another guy and he told her it was not him doing it and finally he tickled a third straight time she screamed and realized it was him and she embarassingly smiled. Thougt i'd share this with everybody pretty cool isn't it
