This is the act of fingering or fondeling a girls vagina.
The word 'tend' is used because sometimes it can be a tedious act; Axe Wound describes the appearance of the vagina or gash if you will.
1. "hey i gotta tend to the tacoone sec" *goes to bathroom*
2. "I'm sure Blake tends to Riley's taco seeing as the are with each other every second of the day."
A mock-authoritative phrase used to degrade or assert dominance in a medieval or fantasy roleplay setting. Often said to a person of color when they’re misbehaving. Meant to be exaggerated and dramatic, not taken seriously.
