1. happening or existing without the knowledge of someone specified —usually used with to <unbeknownst to us rumors were flying> (Merriam-Webster Online).
2. a word that pretentious pricks use to try to sound smarter than they actually are.
Unbeknownst to you, I have been fucking your sister for the past six months.
My dad has been sick for years, unbeknownst to the family.
Not a word pretentious pricks use. An extremely highly intellijated.., (also a new one) word, that only people with common fuckin' sense do. Actually, the proper spelling includes an apostrophe prior to the T.
2. A drug with which you (probably Tracy Morgan or a date rapist) dose another person (probably Jay Mohr or a club girl) without their consent
JM: "So I hit the J and it felt like glass was going down my throat so I vomited immediately and I'm like what the fuck Tracy, and he goes 'You neva smoke PCP before Jay Mohrs? You neva smoke sherm? You didn' smell it?'"
When you miss the memo that you’re invited to something because you weren’t invited directly and the person that got asked on your behalf declines for you.
“Ashley isn’t coming?”
“No she didn’t wanna come.”
“I wonder why. Is she mad at me?”
“I don’t know. “
Meanwhile Ashley’sjust in her room wondering why she didn’t get invited to the party. Who’s mad? Unbeknownst beef vibes.
