dude you can do what i do.. when i see somebody with a booger hangin from their nose i just tell them people around or no. "Hey man you have a booger hanging outta your nose.. i can't let you go around like that" They will appreciate it.
Just be like, " Hey man i don't wanna be a dick or rude to you but i have to tell you this so you don't emberass yourself .... you smell like ass, i'm not even joking. You really smell like ass."
Then procede to tell him that you are kewl with him.. he just need to take better care of his ass.
