When you blow your load while getting head on a riding lawnmower, Then you donkey kick her in the back of the head while she's getting off the mower.
Dude Amy hasn't been at work lately do you know where she is? Ya I heard she's been in the hospital with a concussion after John gave her that Knudson Mule on Sunday.
Knudsen is the most accurate and appropriate way of describing someone who is "lit" or is yet to be "lit". Someone with the last name "Knudsen" either loves country music, or gets tortured by it every year for about one month straight. This is most likely because another Knudsen, in the nearby area, is blasting "Armarillo by morning" on their 14 year old speaker.
