Residuface 

Residuface occurs when someone has an amusing conversation in one room, then leaves but they still have a stupid smile or grin on their face while entering the next room, which often looks moronic to onlookers

"Darn, I was just in the lunchroom joking around with my secretary when I walked out and my boss looked at me and I had a dumb looking Residuface"

e.g. "Residual Face"

Residuate 

1) To find the residue of a function. The residue at an isolated singular point z0 of a function f(z) is defined as the contour integral of f(z) around C, all over two Pi i, where C is a positively oriented simple closed contour enclosing z0 (and no other singularities of f(z)) and i is the imaginary number defined as (-1)^(1/2). Alternatively, one can define the residue as the coefficient of the z^-1 term in the Laurent series expansion of f(z) about z0.

2) To jizz on that bitch's face.

Definition 1:
1) Residuate that ho!
2) Dude 1 - "Dude, I can't residuate this function."

Dude 2 - "Did you try taking the squrl?
Definition 2:
1) Residuate that ho!
2) SQF needs to CTFD and residuate a ho.
