look up any word, like thot:
 
1.
Just like a Dirty Sanchez but, while in the act of performing sex on a female while she is on the rag. You then get oral sex from her while she gets menstrual blood on her upper lip. You call her a varmit while doing this.
While my lady is ragging I make sure to give her a Yosemity Sam
