An M100 is a Semi-Automatic Carbine Assault Rifle made by the American gun company Calico. It is called the M100 because of its high capacity clip of 100 rounds + 1 in the chamber. Was very unpopular due to the assault weapon ban which has since been repealed and M100's are now legal for civilians to possess in their respective state. The military has yet to contract with Calico thus leaving Calico a relatively small gun manufacturer. In some states is also referred to as a "long rifle" making it legal to posess in states with an assault weapon ban.

Surf Dracula Syndrome 

A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.

For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
I watched "Smallville" on Netflix the other day. Dude, it was ten seasons of filler before he finally flew! Major Surf Dracula Syndrome!
