I saw a homeless couple fucking behind a bus station once. I was about 30 feet away. Both totally nude.
I remember being in the 5th grade and hanging out at my friend's in the front yard. He was going to go to his mom's room and ask her if we could ride our bikes up to the park but he said the door was locked. We were sitting in his front yard and could hear his mom moaning his stepdad's name over and over and saying "harder! harder!". Took me a while to register what exactly was happening.
I forgot to mention a story about him - he was hanging out with us (the white boy clique) on a Saturday afternoon. We were at a ghetto movie theater seeing Terminator 3. Some people sitting behind us kept talking out loud and annoying us. And no fucking troll - he (the Watts transplant) pulled out a gun, turned around, pointed it at the people talking and yelled out loud "HEY NIGGA, SHUT YO FAT ASSES UP BEFO I DO IT FO YOU", then he put the gun away and started eating popcorn and watching the movie like nothing happened.
I went to HS with a guy who was a real street thug from south central LA. He was originally from Watts (grape street crip) and he transferred out my way for his senior year of HS. He had tats all over (and this was an era before everyone and their mother was inked up). Carried a gun, spray paint, bandanna etc.
The HS I went to was about 40% white, 40% Mexican and about 20% black. The blacks used to think they were gang bangers because they didn't have dads and smoked weed all the time. When he first came to the school, he tried hanging out with them but he ended up HATING the blacks on campus. They all idolized him and he in return thought they were all phonies, and pussies. He'd only hang out with the white guys. He used to tell us that we were his "niggas" even though we did typical white boy shit (drove trucks, drank beer, watched and played baseball, etc).
He added me on facebook about a year and a half ago and he's got a ton of pics of him with groups of other blacks guys covering their faces with purple bandannas and throwing up signs. He runs some backyard business in which he paints people's cars.
