In no partcular order, and only listing movies I've actually seen:
Big Bad Wolf (I'm a sucker for werewolf movies, but with when you get to the final couple inside of the first 20 minutes, it's time to say - "What's on Discovery Channel?"
Ator the Swordmaster;
Troma's War;
Tremors 3 and 4 (the first one is hilarious, and the second is tolerable);
Deathstalker, Deathstalker 3 and Deathstalker 4 (the second was made as a spoof and it's damn funny);
The Satanic Rites of Dracula (and I like Chris Lee and Peter Cushing - I strongly suspect some serious mortgage payments were due, or Hammer films had some really nasty photos);
Any of the Porky's sequels (when T&A movies can't hold your attention for longer than 10 minutes...);
Alexander;
the Dungeonmaster;
and so many others that I drank so much beer to forget.
