To fap to one's own ego. Taking narcissistic pleasure in one's abilities, status, etc. In a literal sense, ego-fapping is masturbating while looking at oneself (in a mirror, on video, etc.). Typically it is used in a figurative sense in reference to a politician, academic, religious figure, or some other individual who is prone to taking great pleasure in self-aggrandizement. Attention whores often ego-fap when they manage to attract an audience (which generally sends the audience packing, or serves as further amusement).
Academics love to ego-fap; they have luncheons by professors, for professors, simply to talk about how great they are.
<Insert politician's name here> is such an ego-fapper; he just loves to hear himself talk.
The only thing worse than an attention whore is an ego-fapping attention whore.
"The hammer falls" means "this is at an end". The "hammer" falling is that of an auctioneer at the end of an auction or a judge at the end of a trial. The phrase should be used to deliver a dramatic, emphatic finality to the issue at hand.
Usage: "The hammer falls <time (optional)> on <subject, topic, etc.>."
Example: "The hammer falls today on Weebl and Bob. Bob is superior (and Weebl is now much flatter)."

2. Sarcastic: A response which satirically downplays something important. Any usage which is used to satirically highlight a use given in definition 1.
Notes: This can be used either as a "subject" (grammatically) or as a response to another's comment.
