River or lake beer. Beer that has been in an ice chest for a few hours and you enjoy while tubing, kayaking, swimming, motor boating, etc. on a river or lake.

It is important to note that this is NOT the same as a beach beer OR fishing beer; which are similar, but distinctly different beers for reasons I can’t fully explain.

bonus points if it’s thrown to you from the boat/dock
I’ll adopt your word for a different definition: a beer from a non working refrigerator, cooled in the near freezing river. God damn Kyiv, it was 18c today and you still haven’t turned on the fridges in the (beach) produktis?
Hm. River or lake beer for me is a bunch of beers tied together and lowered into a body of water. Usually less than 1m is enough to keep it cool. It’s a different coolness.
