1.) big mother-fucking gun
2.) a 1/2 inch wide (.50-cal) bullet full of whup-ass, dubbed "Browning Machine Gun" after the heavy machine gun it is used in (the M2HB). Barrett also has a full line of Sniper and hunting rifles that use the .50 BMG round. It has the capability to penetrate light armor and an entire engine block of a truck, completely immobilizing it from a fair amount of distance. Not to mention the fact that it would take off the limb of a human if shot placement is correct.
I need more .50 BMG rounds to take out those insurgents!

May 22 Word of the Day
A moment that is generally agreed to have had a significant influence on pop culture and everyday life. While the term was coined by Rose McGowan in context of the #MeToo movement, and is mostly associated with the K-pop community, the phenomenon is universal and a basic component of how culture works.

Real world events such as social/political movements, the election of a new U.S. President, major catastrophes and disasters, as well as entertainment such as movies, music and TV, can all function as cultural resets. Notable cultural resets in relatively recent memory include:

* The Beatles appearing on the Ed Sullivan show in 1964
* The Watergate scandal of 1974
* The release of Nevermind by Nirvana in 1991
* The September 11, 2001 attacks
* The election and inauguration of Barack Obama in 2009
* The COVID-19 pandemic
"The Nineties politically started with the fall of the Berlin Wall on November 9, 1989 and the Soviet Union dissolving on December 26, 1991, and ended with both the 2000 Presidential election which saw the victory of George W. Bush and the terrorist attacks on September 11, 2001 which left people so stupefied that it functioned as something of a cultural reset button." - TV Tropes' article on the 1990s
