A friend of mine and I were reminiscing about "the good old days" and he remembered seeing two young fellows getting ready to "throw down" at a bar...one of them warned the other "I'm tough as nails and twice as sharp!!" 
back at a club which i was bouncing, we got into an arguement with some gang members, so one of our guys was going back and forth with them, one of the gang members said something along the lines of " dont mess with me ####, my name is on the streets , you dont wanna be fucking with me" and my boy the bouncer said " your name is on the streets mother****? my name is below the streets ( or beneath the streets)" . Even at that time with adrenaline beginning to rush i was like WTF does that even mean, i asked him later he didnt give a clear answer
