Pochunka 

A piece of excrement, stool, poop, poo, crap of sizeable proportions.

Louise: Where have you been ?
Nigel: I have been in the bathroom and released a massive pochunka. The local water engineers will be busy for a few weeks.

pachunkachunk 

1) a big fat ass, chunky (as in chunky monkey)
2) Not something you would strive for, or tap for that matter.

Damn, look at the pachunkachunk on that girl, I'm not going home with her...

Pochinka 

A turd, stool, poo, poop, crap of unsatisfactorily small proportions.

Stu: Do you feel better having gone to the bathroom?
Holly: No I strained as hard as I could but only busted out a Pochinka.
