AL: I implore you... please remove WAMPUS, FISHBALL. Someone might actually think we use these words! Do it as a public service for others learning English.

The one where you copied every meaning in the dictionary is ok, I guess, Lingvo is after all a dictionary, so why not copy and paste a dictionary into a dictionary?

+++SCUMBAG

++UNSAVORY CHARACTER (although very diplomatic)

+NASTY PIECE OF WORK (although somewhat dated)

Uly, douchebag - придурок, scumbag - подонок
But неприятный человек does't mean this. It's just an unpleasant character

Elena, you’re going by the Dictionary
again. A придурок is an idiot, moron. A scumbag or douchebag is an unpleasant person, the kind of person you don’t want your sister to date, for example.

OK! Thank you!
