Cheers, in your favorite language of choice.
Slante or salud or whatever language ya fancy if you're following me.
Had an Irish buddy who gave us all flasks for being in his wedding party. they all had slante(sp?) engraved on the front. I guess any type of toast would work.
With that said I did use it to get drunk and it now rests on the bottom of a river that we kayak.
Life lesson #37: No matter how empty a flask is, it most likely won't float in water so don't haphazardly try and toss it to your buddy while boating.
