A shirt on at the beach says it all.
black people seldom take shirts off in the beach. Many of them have that "everything is gay, gangsters wear baggy pants all the time" mentality. They don't say "ask" they say "aks".
I'm a white dude, volley ball, beach activities, swim trunks... I do all that, but when I walk on the streets I wear pants that don't emphasize my legs or butt, nor do I use tight shirts very easily.
