Top definition
a word that directly refers to anything that is of a less-than-adequate quality. Specifically, those ugly jeans you're wearing or the current state of your cluttered mind.

Also: an abbreviation for the horrendously long word abysmal, which to the general public is the most USELESS FUCKING WORD EVER.
Yes, the weather is fucking bismal today.
