Generally refers to a very commonplace handgun cartridge first developed for the 1911A1 Colt Autopistol, available in FMJ and JHP. A rather bulky round with a weight of roughly 11 grams, the .45 ACP is seen as the ultimate manstopper by American shooters. Though it is a sub-sonic round that uses relatively low-pressure charge, its sheer size can deliver enough energy to very literally stop a man in his tracks. On the flip side however, it does not have a substantial amount of piercing power. Other .45 cartridges include the .45 LC (for Colt Revolvers), .45 GAP (Glock Auto Pistol), and the .45-60 high-powered revolver load.

1: A .45 caliber Firearm, usually a handgun.
2: A song written by Shinedown, with arguable many meanings but most certainly not about a breakup. many believe the song is about conformity and the dangers and sorrow of our shallow society.

Referring to Donald Trump. The Daily Show with Trevor Noah calls him 45. In South Africa, 4 - 5 is slang for penis, according to Trevor. Its better than saying his name.
