Kitsa

A very nice person

Kitsa is my favourite person

Thiccpack

The abs OR lack thereof on a particularly fat person
Can be used to describe somebody who has visible abs but is overweight, such as a heavyweight wrestler (1)
Alternatively, it can be used to mock somebody for NOT having visible abs due to body fat (2)
Both are generally used jokingly, between friends or acquaintances.

Friend: hehe hey bro nice thiccpack
Fat guy: aw fuck off I told you I'm working on it

Bilestone

A Bisexual Milestone

Used by somebody who is bisexual, or someone who is a different kind of queer who just likes wordplay.
May be used in reference to traditional stereotypes, but not in a derogatory or harmful way; jokingly.

Guy 1: "ehehehehehe I just achieved a new bilestone"
Guy 2: "...a what??"
Guy 1: "I just got my eyebrows pierced and my nails done teehee"
Guy 2: "ohhh nice"
