for a $2.50 chip?

If this is the case, then I'll need to change my glossary of terms.

But on the otherhand, if usage of a word becomes prevalent for another meaning, at which point is the new definition accepted into the lexicon?

Perhaps a glossary or dictionary of Casino Memorabilia Collectors would have two meanings for the word 'snapper'.

1. A name given to a natural 21 in a blackjack game, following the distinctive motion and "snapping" sound given off when the player gets the 21 and in exuberence slaps the cards face-up onto the blackjack table implying to the dealer to "Eat This!"

2. A name given to $2.50 chips, by casino chip collectors when they mistakenly thought that the definition of 1., above, was a reference the sound made when the dealer plucked a $2.50 chip from a rack of chip as part of the pay-off for a natural 21 in a blackjack game.

Within the context of casino memorabilia collecting, should the term 'snapper' only mean a natural 21 in blackjack, or is there room for two definitions?
