The perfect glass for an afternoon out with the lads can be found here, at breadandbadger. Hand-etched glasses are hard to beat, and this seller has several other types of glasses as well. So good.
Perhaps the best thing Bread & Badger has done, however, is set up this flickr photo group of people drinking out of the glasses.
By the way, I found out about this on the excellent etsyitemoftheday.com.
I do the following fully aware of what it is that I am doing. My wife is an artist, and has sold on etsy herself before. If you don't want to wait for breadandbadger to catch up with your order(who has left a note on her website about how she has slowed down due to pregnancy), you can pick up the glasses pictured below at Urban Outfitters' website. And they're on sale.
(Or you could decide to do something outdoorsy.)
