An idiomatic expression meaning roughly "to explode in a fit of rage and fury", it is derived from the action of a firearm hammer "dropping" -- or striking -- the firing pin which in turn impacts the round and causes the mini explosion that results in a bullet or other projectile being launched at a high velocity out of the end of a barrel.
The expression can be used in several different variations with the above definition: 1) ...part. in a draconian way 2) ...leaving a wake of destruction in its path 3) ...against a very specific target with precision; etc.
"I have a clear shot of the target. Requesting permission to engage."
"You have the green light. Drop the hammer on that motherfucker."
BANG. Bad guy fall down.
A sexual act involving 2 people and a vehicle. While a male is receiving oral sex in the driver seat (While operating said vehicle) from a female in the passenger seat, the driver swerves to intentionally hit an object, activating the airbag and thus taking deep-throating to a new level. Also known as the triple H (HHH). Originating out of Holland, Ohio.
Sally needed reconstructive surgery after receiving the Holland Hammer Head from Gilbert in his '97 Ford Aspire.
"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)."
