20XX 

The year when something becomes completely optimized due to being so far into the future.

In the year 20XX everyone plays fox. The Melee players of the future convene in holo-New Jersey to decide the ultimate Smash champion at APEX 20XX. Will it be the immortal Mecha-M2K, Mango Jr., or PewPewU who is just turning 21?

20XX 

The hypothetical year in which players play perfectly and where the winner is determined by other factors than skill.

The year is 20XX. Everyone plays Fox at TAS levels of perfection. Because of this, the winner of a match depends solely on port priority. The RPS metagame has evolved to ridiculous levels due to it being the only remaining factor to decide matches.

Windows 20XX

The version of Windows where Microsoft replaces the Windows Kernel is fully replaced by the Linux Kernel and Windows just becomes another Linux distribution with a fancy Windows skin. WINE and Powershell will also be integrated out of the box to try to convince people it is still Windows.

Person 1 "Wow can you believe Microsoft finally made Windows stable with Windows 20XX. I haven't had a blue screen in weeks!"
Person 2 "That's because you're using Linux."
Person 1 "What's Linux?"
Person 2 "BTW I use Arch."

Cheeks 

An Irish phrase meaning shit, derived from ass
(Not to be confused with the literal description of one's buttocks)

"Did you hear the song Aylek$ dropped?"
"Hardly. Her music is absolute cheeks."

"My boyfriend say LaFlame is cheeks."
"Tell your boyfriend I said it's his mixtape that's cheeks."

Breadhead 

Someone who is addicted to obtaining money and building wealth. A money addict and fanatic. Breadheads often work more than one full-time job, and some even participate in illicit activities to "obtain the bread".

A breadhead is like a crackhead, but for money instead of crack.
