This is brilliant! I could kiss you, CJ!

Fortunately covid restrictions prevent that.

Excellent stuff! Well done. This has always been something that I've found us TF fans use a lot, or possibly too much sometimes. I've always wondered what it is like for new fans joining the Internet chat groups and wondering what the heck we are talking about.
This should be used as a guide on all TF websites.

But hey! You forgot us!

And the fact there's an ocean between us....


*sobs*

[Benn]

What is an ocean but a damp road?

[Philip Ayres]

Surely a river is a damp road?

It's a wet road....
... getting from here to Texas

[Shockprowl]

It's a wet road,
Getting from here Texas

But I'll sail true,
The wind is in my sails.

I can stand the storms at night,
Salt spray in my eyes

One day you'll teach me how ride,
Rustle livestock side-by-side

'Cos I've got faith, in our Texan
I'm going where the cowboys roam free!

I've strength, to believe
I'll look good in a Stetson

I've got faith, in our Texan
The Great Plains will not tame me!

I can reach, sheriff's star...

'Cos I faith...

I got faith...

Faith in out Teeeeee-xaaannn....




(slightly stereotypical perhaps... apologies to any Texans reading this.)

Been steadily updating since I posted the list. I think it's just about maxed out.

Kind of interesting that BH, which is a fairly insignificant subline in the grand scheme of things, ends up being referred to often enough that it has a common shorthand. While all of the subline/rebrands of UT are never referred to at all. No one ever refers to Armada: Unicron Battles toys as UB. No one ever refers to Energon: Powerlinx Battles toys as PB.
No one refers to the Beast Machines Motocycle Drone as BftS (battle for the spark) Motorcycle Drone, or NuRID Galvatronus as CC (crash combiners) Galvatronus.
