1-During the act of sexual intercourse placing the thumb in her asshole then making a thumb print on her ass with the shit on your finger from her asshole. (easiest during dogystyle sex)
2-During sexual intercourse grabbing her ass so violently and for long enough time as to leave a red thumb print on her ass from the verocity/length. (similar to Five Star but only the thumb is counted and is not made from a slapping action)
Dude, i left a TOHA last night!!!
You can see her TOHA when she wears a bikini.
