Punching the pastrami refers to the act of masturbation for anyone with a vagina, due to the fact that some labia appear similar to certain types of lunch meat.

The vagina bearer's equivalent to "beating one's meat."

Thought to be used first by indie musician Morgueanne di Monica, though she claims there may have been someone before her to use it. She explains that the thought for the term "punching the pastrami" came from a quote from the movie "A Million Ways To Die In The West," where the character Eddie describes a vagina as looking like "a firecracker wrapped in roast beef."
Sorry I didn't call you back right away, I was punching the pastrami.

Dude, you'll be fine. Just go home, take a bubble bath, punch some pastrami, and sleep it off. You'll feel better in the morning. I promise.
