When a female or Bitch is sleeping with they ex-boyfriend while having a boyfriend..This bitch will later catch a std which means her coochy will smell like a sewer rat. This also happens when you try to steal people's boyfriends by popping pussy for a real nigga aka a SRB (sewer rat bitch).
Damn she let you fuck again, you fucking with a sewer rat bitch
