Thwack-Back

When having sex with a male(homosexual or transexual) and their penis slaps against you.

As we fucked, her penis kept hitting my leg, causing thwack-back

Twackbacked

1: Used to describe a tweaker who is so high that they cannot focus on any task.
2: In the tweaker society, means to be super relaxed and chilled.

1: Check out Roame! He can't even figure out how to paint that wall. Bruh is twackbacked!
2: My bez fran and I have finally gotten a buzz. Now we're twackbacked and running tats.
