Blunderfuck 

Realizing fucking someone is a bad mistake.

Dude I blunderfucked Chun's mom last night and it was not good.

lusterfuck 

When a casual hook up becomes questionable because of a possibility of feelings being formed for the other or rather just lack of communication of what the other wants or is looking for, besides sex

I'm in a total lusterfuck. Like he asked me out to a concert and we hooked up a few times but he doesn't talk to me much and I don't know if he likes me or not

Underfucker 

The person who's only goal in life is to make a public speech impossible to perform. Also known as heklers

- Every time I try to present something she is always there to sabotage it.
- Gosh, she's such an underfucker!

underfuck 

When a person comes up with ANY excuse possible in order to just NOT tell the truth out of sheer stubbornness.

She totally underfucked herself so hard when she refused to just let them know that she had mononucleosis instead of covid, what a stubborn bitch.

Underfuck 

What my wife does to me in bed when she's really really worked up and liking it - trying to have an orgasm - she usually does it when a good man takes his time and.... well you know what comes next. But yeah underfucking is amazing if you haven't already tried it I'd highly suggest you train her up to grind from the bottom upwards. Peace.

Underfuckitude 

Not giving a fuck enough, additudinally, to be detected as having concern.

There was nothing but an underfuckitude in their lack of effort.
