the.com/party boat

means A boat trip organized as a floating party, typically with music, alcohol, and a crowd more interested in revelry than scenery.

from A straightforward compound: 'party' (from Old French 'partie,' a group taking part in something, later extended to festive gatherings) plus 'boat' (from Old English 'bat'). The term doesn't trace to some clever coinage — it's a plain descriptive label that caught on as chartered pleasure cruises became a popular way to host celebrations, bachelor sendoffs, and general mayhem on water instead of land.
