Bumcrumpling

Can be used in any way, almost like Lobstromonus. Usually to emphasise and exaggerate something.

It can be negative, positive or anything else.

E.g.

"Oh, wasn't that a bumcrumpling defeat just the other day?"

"You are a bumcrumplingly beautiful man."

"We had a bumcrumple of a time."

"Well, we went back to his place and had a bumcrumplingly bumcrumpling bumcrumpling session, if you get what I'm saying. We really bumcrumpled a good deal."

"You are such a bumcrumpler!"

BumCrust 

Originating from Egypt, Bum crust describes the phaecal matter that is not properly wiped from the rectum after excreting phoeses. Consequently, the remaining phaecal matter hardens and becomes entwined within the Pubic hair to form what is known as "BumCrust". See arse biscuits

"Ah shit, we ran out of bog roll, I'm like a bum crust factory!"

-or-

"Uhhhh, there's all bum crust in ma pants, Anyone got Scouring pad?"

bumchums 

3 n00bs who play WoW MMORPG and put even the retards who play that game to shame, they like the sexings, however they never get it and they think they are so uber l33t even though they get their asses kicked at arena battles and PvP, they own almost no tier pieces and spend most of their time having no life and bumming over each other. (unless with each other) see koigen, hyrex, arkot.

Arkot: hey guys wanna try at PvP.
Koigen: Yeh sure we can go AV and pwn some n00bs.
Hyrex: after that we'll go and show off our tier 4 piece to everyone.
*guy wearing merciless gladiator set walks past*
Guy: stupid n00bs you suck at PvP you have no good armour.
Arkot: ah screw this wanna go have some sexings with each other?
Koigen: yeh sure.
Hyrex: we are bumchums after all
