Man. It must suck to grow up having a super hot mom that dresses like that.
She can wear what she want, no one would say anything if she was in a gym.
I remember when I was in middle school, a few of the neighborhood kids were playing basketball. One, the littlest out there, was Bobby and another, the biggest out there, was Gene. So we were balling, and then all of a sudden one of the guys basically stops the game and points to a woman walking. It was Bobby's mother and she was outside exercising. So she was wearing these super short shorts that were showing all the cameltoe and a sports bra that barely fit. So of course, everyone was staring until she was basically out of view. Then Gene turns around and was like "Damn Bobby, yo' mama's a hoe." Everybody started laughing, but it wasn't on some typical "Yo Mama Joke" type shit. Everybody was basically thinking the same shit Gene said, but for real. Bobby was a quiet kid and didn't want any problems, but you could tell he felt like he had to say something to defend his mom. So he was like "Shut up, you fat mutha fucka." Well, Gene didn't like the audacity of Bobby saying that to him, so he took the basketball, which was Bobby's, and kicked it in the lake and was like "Go get it bitch nigga." And basically everyone walked off. The whole shit was kinda funny, but I couldn't even laugh. I saw the look on that kid's face and it was pretty pitiful. He was soft and kinda got put in a bad situation and suffered for it.
On topic, anyone who complains about that chick's outfit must not have been to a black Chuck E Cheese before. I take my kids to one every now and then, and half the chicks in there be dressed like they either just got back from the club or heading to the club after their kids are done.
