Fatal Deviation 

The best and only Irish kung foo movie. So bad it never had a theatrical release and can be viewed on youtube.

Starring real-life martial arts enthusiast James Bennett and Mickey Graham from Boyzone.

I just used my fatal deviation...

Fatal Attraction Fart 

Its a fart that is like a clingy and creepy ex girlfriend that won't go away. Its when you fart and it just stays in your pants and wont disappear. They show up and the worst possible times. Most of the time they skulk up like an ass goblin and surprise you. Frequent sightings have been during dates with hot chicks and meeting your chicks parents for the first time. Bad timing!

I was at the party the other night ready to hook up with this chick when I had a fatal attraction fart that cleared out the room.

One careless mistake wrecking an otherwise flawless execution of some mischievous behavior.

[fatal] [ass] [breath] 

An unbelievably horrendous smell emanating from the orifice of the mouth. Could very well kill a small elephant.

Shit man, I can't make love with you, you have some fatal ass breath!
