its the best way to troll people.
The night i 'broke up' with my exgirlfriend, I studied her myspace and facebook and found all of her other 'boyfriends' (turns out she had multiple fuck buddies in different towns) and let them in on what was happening. They all dumped her and sent her nasty voicemails and she lost ALL of her friends that week, I pretty much ruined her life. She also gained like 70 lbs in the months following, I'm pretty proud with what a success my little scheme was.

I ran into her a few months back at walmart, and put on a troll face, and she just clutched her new boyfriends hand, and said "WALK." to him, and speed-walked away from me as fast as she could
