Flabermac 

When a guy or girl is approaching another person on the dancefloor whilst discreetly dancing. Usually to try and "get with" that person

"I saw Leroy starting to flabermac towards me on the dancefloor and i tried to get away"

"for word?"

Flaberganus 

the flap of skin between your balls and your anus: also know as taint or the DMZ.

We have been riding bikes all day, my flaberganus is real sore.

flabberjack 

Giving a homeless man (or woman) a sandwich in exchange for a blow job.

We were downtown last night and decided to go flabberjack the local bums with our left over Subway sandwiches.

Flabergate 

1) The act of sweating from man boobs.

2) When a large man with man boobs sweats enough to form the damp outline of his man boobs on his shirt.

Did you see that old man with moobs jogging? He was flabergating enough sweat to fill a bucket.

I tend to flabergate when I failasturbate.
