what losers say they did when they "gave it their all." only in the lexicon on losers.
dad: yeah you lost the game and embrassed the family son, but you gave it your best effort...
son: i know dad, thanks.
dad hits son
Giving all that you can in a given situation, but always failing to meet some one else's standards
Try as I may, my best effort was not good enough for my girl friend, so she left me, stupid cunt
Working to one's ability, rather he or she fails or succeeds.
Put in your best effort.
giving your best effort is when you try your hardest.
mom: you got an F on this paper!
son: i tryed my hardest!
Was that your best effort?
Nope, but good enough.
To make ones greatest attempt
Yo im going to make my best effort to save my money for a new car.
Not good enough. Ever. So just stop trying.
You'll never be good enough.
