aftermilk 

The milk left over after a bowl of cereal. It is usually cold and sweet and often contains small cereal particles.

My favorite aftermilk is from a bowl of Cookie Crisp because it is cold and sweet and has little lost choclate chips in it.

aftermarket

Parts made by an outside firm to replace OEM (Original Equipment Manufacturers) parts. Commonly used in automotive purposes, but the aftermarket exists in virtually every industry.

In other words, these are NOT "Genuine <fill in name of manufacturer> parts." The quality of aftermarket parts can vary widely, some engineered to be better than the originals, some poorly fitting and otherwise inferior crap. Caveat Emptor when buying aftermarket parts! But sometimes when the original parts are discontinued or the manufacturer has gone out of business, the aftermarket may be your only choice.

NAPA and J.C. Whitney are two of the larger aftermarket auto parts suppliers.

Quality Discount Press Parts and AAA Press are pretty much the only aftermarket suppliers of note in the flexo printing industry.

Afterkick 

An unpleasant feeling some people infrequently experience when taking a drag of marijuana. Some report it as their brain exploding, or swelling of their heart combined with anxiety. It's only temporary and goes away after a few seconds.

Take the spliff away dude, this afterkick is killing me.
