Ugh Son
Slang for letting anyone around your immediate surrounding know you are tight as hell and that you should not be messed with. You may suddenly stand up in a school courtyard and start throwin down some "Ugh Son Ugh"'s to intimidate those punk turds steppin round your hood.
"Right, Left, Right, Left, UGH SON UGH.. Yo that jackets tight yahhhmean?!" (And you'll take that shit off that hoe who's frontin cause you so down and you fresh like cool-breeze son nobody gonna front on you!)
