Any congregation, gathering or joining of beavers (genus Castor) to party, boogie and generally “get down.” Beaver parties are easily identified by two factors: 1) the presence of beavers and 2) hearing the German techno, beaver party anthem “Sweaty Beaver, Hot Dam.”
There’s a beaver party at my dam tomorrow at 7.

The best beaver parties happen in the hottest dams.
