When someone contracts a form of VD. The infection cause a burning sensation when urinating (peeing, pissing). Usually cleared up with a trip to the doctor.
1)I messed around with that white girl from the club but she was nasty. She gave me VD, had me pissing razor blades in the morning.
2)Shelly cheated on me; I was pissing razor blades. My dad had to take me to the doctor.
3)The condom broke and I caught a bug from Marcy. I've got to go to the clinic because it burns when I piss. Feels like I'm pissing razor blades.
