818
Used by National Socialists (Nazis) to say "Heil Adolf Hitler." H is the 8th letter in the alphabet, and A is the 1st. Hence, you get 818. Also see "88."

818
"The Valley" -- the San Fernando Valley that encompasses the northern portion of the City of Los Angeles (although it constantly wants to secede). Known for Valley Girls ("yeah, like gag me with a spoon... as if!"), the Galleria and a climate significantly hotter than the other side of the hill and thus rivaling Hell. Also the porn capital of the Western Hemisphere.

818
818 - (n) An area code in the San Fernando Valley ("the Valley") area of the Los Angeles, north of the Santa Monica Mountains.

The area code was featured, in a somewhat derogatory manner, in the movies Go and Swingers.

People (likely due to its use in Go), will sometimes use it to refer to someone going apeshit.

818
The area code of The San Fernando Valley in Los Angeles. The vslley is huge, consisting tons of L.A. suburbs. '818' is the gangsta way to call it, as there are lots of gangstas down in L.A., so yeah. The people that reside in the valley (particularly the Persians), always say things like : "2Live 'n' die in tha 818 area." Even through in contains only suburbs of Los Angeles, gangstas still live in there. It's still the 'safe', 'unhard' valley, but there are 'hood' cities in there (i.e. Reseda, Sherman Oaks, Woodland Hills, and especially Pacoima!) If a person resides in the valley, it is 'cool'. Also the 818 is the birthplace of the phrase Persian Pride. Probably down in Reseda. A shit load of Iranian-Americans reside there.

And by the way, I reside in Woodland Hills, Los Angeles, and the are fucking dangerous places to be at night.
