A word that only faggots/potheads in Southeastern Idaho use. Nobody knows what it means except the people who say the word. There is another variation of the word:
egglegal
There may be more, but none have been heard.
It is said that eggleast is a faggot way to say "at least" but, again, nobody is 100% sure, except for the people who say it.

This strange word was originated in a small Idaho town, due to the mispronunciation of "at least" and was carried out by a group of young potheads. It is also used when one does not know what to reply- as a distraction. Other uses of the word have been egglast, egglegal, ect...
