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."

Poker terminology.
When someone raises early (usually pre-flop if playing Holdem) just to push other players around, and you just can't take that smug grin on his face, you re-raise a ridiculous amount and "drop the hammer." This most often occurs during a Testosterone Fight, and the object is to make the other player put his testosterone hose away and fold. Since it is pre-flop, this has nothing to do with the cards you have, just plain good ol' fashioned balls.
