What Is The Worst Dare U Have Ever Done?

The worst dare I've ever done was on the bus on a school trip (year 6). The whole bus was playing Dares. I didn't want to play but my friends persuaded me to. When my turn came, I was dared to kiss the boy who was sitting across from me everyone turned round to stare at me so I lent across and kissed him on the cheek! I didn't like it and everyone cheered. Then my friend had to do the same and she wouldn't do it so I pushed her forward and she did it too!
That has been my worst dare so far... (The boy has hated me ever since - I never liked him anyway!)

Baby sit little girl that liked me take shower make out touch my junk and suck her stuff

This wasn't happened to me but one of my friend had the most worst dare, I have ever experienced in this game.
We were playing with a group of guys and girls and she chose dare. One of the guys said he want you to kiss both of her butt cheeks, which she did not want to do. She told him that she would do it in front of the group if he was willing to have other people
watch and he drop his pants in front of the group. He wasn't willing to be
naked in front of everyone so she thought that she would off Scott free. However, She got a
little cocky and made the offer to anyone who was willing to drop their pants,
thinking none of the guys would do it. Well, her best friend said she would, and
of course they guys said she had to, so she ended up kissing her best friend's butt.
