(noun/verb) When the male
reproductive organ, otherwise known as the "penis," inadvertently fails to penetrate the female
reproductive organ which, for convenience sake we will henceforth call the "vag," and proceeds to take the aforementioned penis and slaps the female counterpart
in the face with the tip followed by a vigorous reentry.
Example 1:
Male A: "Yo man, I couldn't find the hole, but
it's all good, I tip slammed her to remind her who has the bigger penis."
Male B: "Word."
Example 2:
Male A: "She was so tight
the only thing I could do was tip slam her."
Male B: "Nice."
Example 3:
Female: "We can't,
I'm on my period."
Male: "It's straight, I'll just tip slam you."
Female: "Dope."
