verb:
The act or practice of masturbating in public view, especially when inadvertent.
adjective:
A descriptor for one who is likely to be caught masturbating in public, or who is known for doing so.
Note: Not to be used as a present participle. "Toobing," therefore, is incorrect. Toobin' is the complete word. One is Toobin', or he (or she!) can be a Toobin', if used as an adjective.
Origins: Used in reference to Jeffrey Toobin, a prominent legal commentator who was caught inadvertently masturbating on a video conference call with his colleagues.
verb: "Ah man, did Marco get caught Toobin' again? That's the fourth time this year!"
adj.: "Do you know Sandy, from accounting? She's a real Toobin', which I find awesome but HR apparently doesn't approve."
