fappo 

War cry declared right before collision with an object. Similar to "cowabunga," "oh shit" and that George of the Jungle yell which-I'll-be-damned-if-I-can-spell-out.

The term was made famous on the internet by a photoshopped Spider-Man comic strip in which our hero mistakes an overturned truck for his long-term arch-nemesis and proceeds to assault the truck by rope-swinging straight into the side of it.

Spidey: "My doctor's retarded. I don't have a brain tumor...say, if it isn't my old arch-nemesis, a truck!"

Narr: SPIDER-MAN GIVES CHASE!

(Spider-Man swings down toward the truck)

Spidey: "Fappo!"

(Spider-Man collides with truck)

fappo 

A word that most likely originates from the word "Fap" which is synonymous to "masturbate". To call someone a "Fappo" would then be similar to calling someone a "Wanker".

That guy is a total fappo!

fappers delight 

Making rhythmic music while your masturbating. one of the earliest forms in the genre of fap music; example;

(non vocal)I said a hip hop the hippie the hippie
To the hip hip hop and you don't stop
The rock it to the bang bang boogie
Say up jump the boogie to the rhythm of the boogie, the beat - "One Hand Mike"

(vocal)
Now, what you hear is not a test, He's fapping to the beat -"Big Spank Hank"

-end --cut the lights. stop the dancers.

while on paper it may have looked like one man was rapping, he was not rapping. What you actually witnessed was one man beating off.

my grandpa use to play fappers delight for me and my brother after school. it was traumatizing to watch and it ruined my life but it was worth it. its more then music, its fap music,
