Five By 

Similar in method to a Drive By. A person in a car or similar vehicle, while driving past a pedestrian, reaches out the window and gestures for a High Five.
The Five By is completed if the other individual outstretches their hand to meet with the driver's.
This act can be made more impressive by Five Bying a row of pedestrians, two vehicles participating in the Five By with one another, or alternatively the driver and passenger(s) in the same vehicle all Five Bying simultaneously.
As the latter is significantly more difficult, bonus points should be awarded upon successful completion.

I just Five By'd this chick on my way here. I think I shattered some bones in my wrist but it was so worth it.

Five-By

When two people are approaching one another at an undefined rate, high five one another without stopping forward movement, and then continue to walk in opposite directions. A portmanteau of drive by and high five.

Yeah, I just gave Becky a five-by in the hall. It was awesome... High Five!

Five by five is a radio communications expression that means 'loud and clear'. One of the fives represents the S units of reception strength. The other five is a rating of the signal clarity. Five by five is a good, clear signal. The radio use of this expression goes back to the 1950s: "'All right, testing, one-two-three-four. . .' 'Five by five, Mr. Holloran!'" (Hunter, Blackboard Jungle, 1954).

The more metaphorical meaning, popularized by Faith Lehane from the television show Buffy the Vampire Slayer, wasn't recorded until the 1980s.

The use of the word is primarily used in the military, or when discussing something similar.

"'I hope everything's all right.'
'Yeah, everything is five by five'"

Loud and clear. From military erminology. Old radios had two readings. Loudness and clarity rated from 0-5. Thus five by five means literally loud and clear.

How's my signal?

Five by five.

Term meaning everything is OK.

The term comes from old radio slang. When communicating over radio, the operator would report the strength and clarity of the signal on a scale of 1 to 5 each. Therefore, if a radio operator described the signal as "five by five" it meant it was both loud and clear.

I don't use the phrase "five by five" because they use it on Buffy.
