Maine thing? No. My nickname is “Gus” Many, many years ago I wasn’t the stand up citizen I am today. At certain venues, I’ll leave that to the imagination, someone would yell GUSTO! We’d all, at least me, would raise the glass of whatever beverage I was drinking and down the rest. I was usually the last man (idiot) standing at the end of the night playing that game. Then I would drive everyone home. You have to remember this is the late 60s early 70s.
Over time my nickname grew from Gus to……….
Gusto!
