1.
The act of pleasuring oneself to the words of another party's flirtatious phone call, or other form of message, without that party being aware of one's pleasure.
"Dude, I think I'm a dad."
"I didn't know that could happen from flirping. Must've been a good connection."

To flirt and creep at the same time.
Dude, did you see that girl flirping?
