A Knudsen
A Knudsen is when someone sits on a bed and the other person just yaps about weird stuff like the history of socks or why the moon is a bad listener.
My mom sat on the bed while my dad talked about why socks are the worst invention ever.
My friend's Knudsen was just a 45-minute lecture about why the moon is a bad listener.
My cousin's Knudsen involved a 20-minute rant about why socks are the worst.
