The act of using your finger as a surrogate toothbrush after having forgotten that you just used said finger to finger a bitch.
Last night, this bitch I was hooking up with stuck her tongue so far down my throat that I puked all over her floor. She wouldn’t let me use her toothbrush, so I had to use my finger to brush my teeth instead.
Girls try to gross each other out with antics similar to those of adolescent boys. Basically, the aggressor will rub her puss then swipe the juice across the upper lip of another girl. More impact can be had by attempting the maneuver when hygiene has be compromised, such as after a long workout or swimming in a pond.
“Becky pussfingered me after gym class today!! I couldn’t wash the stank off my lip all day, I’m gonna get that bitch!”
