A meaningless phrase that prefaces relevant information. It is basically unnecessary if not redundant, as one is engaged in the very act of “advising” when issuing a warning, imparting knowledge, or giving advice. “Please be advised” is used excessively by people in law enforcement and sometimes by those who became serious about life at a very late age, and now maintain blogs that purport to warn the public about what is largely one-sided, uninteresting crap.

A person with an outwardly dominant, masculine, or aggressive personality, but who also enthusiastically takes on the submissive or "bottom" role in the bedroom.

Essentially meaning: "I am an asshole." The beginning words from someone or something that is about to reject, worry or disappoint you.
