douche knot 

Those guys who you see walking around with hair just long enough to tie into a little knot on the top of their heads. Can often be seen in the local gym usually sporting a sleeve tattoo and a large beard.

Look at that cunt over there with the douche knot

doucheknocker 

A female version of a fartknocker or a buttknocker.

While I was flying the drone, I "heard" a jingle for Bob's Discount Furniture but with altered lyrics.
To wit:

♪ Bob's Bob-O-Pedics ♪
♪ From your åšs#Ø£€ to your ṕ€nµs ♪
♪ Some doucheknocker neutralised a hat!!! ♪
{~850ms silence}
♪ Bob's Bob-O-Pedics! ♪

douchknot

Alternative description of the "man-bun" hairstyle.

Wearing your hair like this informs strangers that you're most likely a douchebag, before you even speak.

That guy at the party had a douchknot.
