Jumping genres, I've seen several badly named ships in various Star Wars games due to a party (of smugglers of course) with a propensity for outlandish paint-jobs and hacked transponder codes. Of course, their stand-by home-away-from-home was some disturbing amalgam of a YT-20-something (lore was not my strong suit in this system) originally named Black Betty.
In the course of ~20 sessions and 8 systems (~20 planets, I think), they changed her name to
No Ship of Consequence
Error Ship 404
Name-of-Ship
Rolling Rock
Free Beer
Full of Bees
Lucas' Folly
Padme's Shaggin' Wagon
Kilt Lifter
Don't Look Here
A Moon
Heart of Tungsten
Badlatin Biblicalname
The Final Form
Blue Moon
Pure Communism
Gungan Pride
The All-Head Pint
Too Fly to Drunk
Casual
and my personal fave: The Wet Wookie
These were mostly groan-induction manifolds, which I got to witness from across the room, as I had a bad habit of taking heavy-weapon users and winding up in ugly melees (i.e. dead/comatose) at the start of any given adventure. This worked out well enough, since I was never totally into the SW d20 system (tastes & accounting...)
