Sarcastic response, usually aimed at twats (eg. pool king)
When a shit joke is cracked, "tchyeah" is the most effective way of making them feel smaller than a ginger's penis.
Can also be used when someone is bullshitting, or randomly when you are pissed.
"Ere lads, I've got a well funny story for you..."
"TCHYEAH!"
"I shagged this well fit bird last nite..."
"TCHYEAH!"
"That'll be £2.20 please mate"
"TCHYEAH!"
verb: To "fight the mong" (also to "fight it")
This usually means that instead of monging, you're going on a trek.
It can mean simply keeping your eyes open, or even mean picking your drunken self up off the pavement. How you "fight it" depends on how monged out you are.
"Let's play football - come on, fight the mong lads!"
"Fight the mong Eric, it's closing time for fuck's sake"
