Input: Text: obligatory this didn't happen today. happened when i was 16-17. 

during my high school years, i had received my first xbox. and i was hooked. playing call of duty with my friends was some of the most fun times in my high school career (unfortunately). 

well part of the fun, was having a kick ass gamertag. i decided i was ready to change mine and wanted one that top nearly all gamertags. after some brainstorming and trials, my gamertag became isawdemeyeskids. it was somewhat witty and dark, so i loved it. 

fast forward a month, and i'm playing in my basement, and one of my dad's old best friend comes over with his 7 year old son. the son also plays xbox and sees me playing call of duty and we start talking about camos and guns that we like. then, he wants to know my gamertag. i obviously didn't want to give it to him, so i just pretend like i forgot it. so he stands right next to the tv, and writes down my name when it came up for getting kills/killed. fast forward another 2-3 days and my dad calls me upstairs. my dad's best friend was apparently not too happy his 7 year old son added a person who claims he sodomizes children. my dad was livid. i've heard him curse less times than i can count on my hands, but in this rant and lecture, he looks straight into my eyes and yells, "do you think butt fucking kids is funny?!" which naturally i started to chuckle, which lead to more anger. lost internet for a couple of weeks and they made me change my gamertag eventually
