<human>: Ok, so when I was 16 I had been dating a girl for a month, when she told me that she had fucked a guy that I knew...that hung around in my friends, no one really liked him. 

So obviously I dumped my girlfriend. The guy that she cheated on me with then started to date another girl. This girl happened to be a well known bully in my area to other girls. Around this time he thought he could hang out with me and my friends when we used to get drunk. One day he brought a bag out with him and confessed to one of my friends that he brought along with him one of his girlfriends cuddly toys that she adored.

My friend told me and all I could think to myself was REVENGE motherfucker! He, some friends and myself crashed over at one of my mates houses. When he fell asleep I took the toy out of his bag and cut the head open with a pen, making a massive hole that couldn't be repaired.

He woke up, saw the toy and started crying. He then proceeded to phone his girlfriend and got dumped straight in front of us. The reason she didn't believe he didn't do it was because all my friends backed me up, instead of him.

Provide a brief overview of the text.
<bot>: This guy fucked my girlfriend. Started dating a bully, so when she gave him her favourite cuddly toy, I ruined it with a pen and he got dumped the next day while crying in front of everyone.
