XtraCards

A Bloons TD Battles mod which adds TONs of new Battle Cards in Card Battles so as adding some custom new Towers and some returning ones from BTD6 (e.g. Druid Monkey).

Player185: "You wanna play some XtraCards?"
Player380: "Sure, why not? I hope it's amazingly good and vivacious at the same time bro."

xtrapolis

A goofy EMU train from Melbourne thats notorious for being bouncy and bumpy. The PIDs doesn’t even announce or show the right station.

Even a 40 year old Comeng with life extension refurbishments is better than this piece of shit.

Runs on nearly every train line annoyingly.

Ryan: “Oh fuck billy look we’re going on an Xtrapolis”
Billy: “Ughh not the Xtrapolis! I would rather go on a Stage 3 Comeng!”

Xtrainer

Xtrainer: A modern trend where people buy luxury trainers (like Nikes), not to wear, but to collect and trade, sometimes becoming highly profitable as their value rises—like a stock exchange for sneakers.

example:He bought a limited-edition pair of Jordans and the price tripled overnight. He was buzzing.

Lee: Bruv, I went round to the young lads from work—help them fix his computer—and he’s got boxes, and boxes of Nike trainers. But he’s still wearing these old scruffy ones! I said, 'Why not wear those nice ones instead?' And he goes, 'No way, I'm an Xtrainer, LOL.

Frank: Bruv, this Gen Z lot are proper funny bunch—they don't even wear them out, LOL.

Lee: LOL.

Frank: LOL.
