Indifferincel 

An incel who knows that nobody likes him but is ok with that and is perfectly happy being alone.

Incel: *I hate women for not liking me!"

Indifferincel: *Ehhh whatever.*

indifference 

The lack of concern of one's actions in respect of the impact it may have on another, and a casual display of ignorance when you have been found to be utterly liable

The bastards didn't care, all they were, was walking indifference

Sexy indifference 

One’s sexual appeal as manifest through the appearance of not caring, whatsoever, how they appear. This is not to be confused with being classless, boho chic, homeless, attention-seeking in trashed street wear or unsanitary, but rather, sports reasonably priced items that fit relatively well, are relatively clean and involved very little thought, as well as limits grooming and engages in frequent, but not obsessive fitness. Think Ben Affleck (most times) and perhaps above average looking women with healthy BMIs who wear Havianas or worn-in Chuck Taylors. Also, this person wouldn’t care, whatsoever, about being sexy indifferent - they just are.

When he wears his crocks, a t-shirt and jeans to work, Ricky exudes sexy indifference. He literally does not give a fuck what anything thinks, and I don’t even know if he knows it, and if he does know it, he wouldn’t care or change in the slightest way. Sighhhhhh, so sexy.

Second Base on Defensive Indifference 

When a guy and girl are making out and the guy continues to try to cop a feel despite the girl moving his hand away. Eventually she gives in and allows him to reach "second base on defensive indifference."

Guy 1: Last night I got to 2nd base with Sally!

Guy 2: Really?!? She let you touch her boobs?

Guy 1: She didn't want me to. But I was persistent, so she allowed it. I guess I reached second base on defensive indifference.

Guy 2: Sweet.

Indifference 

The lack of emotional or physical responsibility when directly responsible for any calamity which might ensue, using ignorance as a defence mechanism rather than accept some form of liability.

The bastards didn't give a shit. All they ever were, was indifference!
