off by one 

Off by one or OBO is a common error in computer program whereby a loop executes one time too few or too many. It occurs most commonly with complex vector or matrix scans.

Programmer 1: This program doesn't work. Take a look and see if there's anything wrong.
Programmer 2: Oh, this for loop is OBO. You aren't scanning the whole array.

off by one 

An "Off-By-One" (OBO) in a non-programming context is the act of a touch-typist beginning to type with their hands one key offset from home position.

If the typist in question types fast enough, the resulting nonsense string of gibberish resembling a 14 year-old's SMS history or YouTube comment may actually be sent/submitted before they notice what they've done.

Ex 1:

Ex. 2:
Carly1992: Wanna come over to my place?

TCAPreditorBate: totally* Sorry, off by one

schmegegge 

Yiddish slang word meaning bullshit, baloney, hogwash, nonsense, crock of shit or hot air.

I don't buy the schmegegge about Morty sleeping with Moira.
His version of the story was pure schmegegge.
The whole schmegegge was made up to get Liz a little bit of attention.
