So NOT up on the Popular Sex Culture Lingo

Excuse me (taps mic)
So when did the terms laid-up, kickin' it, or chillin' become the equivalent to what my old Pastor used to say, shackin' and smackin'?!
I don't know if that's just a way for someone to talk under your clothes, meaning: see where you are sexually or if the vernacular truly has changed amongst the masses and those statements are code for:
Don't bother me, I'm getting booty!
Or
I'm with a significant other-type

Just to be frank, although my name is indeed Khrystian! I'm just saying! Here's what these following terms mean to ME:

Laid-up-> laying on the bed, couch or floor. Usually significantly over the eight hour requirement for a good nights rest. Preferably in your pajamas or some other alternative that you wouldn't ordinarily leave out of the house in. Occasionally family members or someone rather close to you could be present but don't play an active role in the equation. All forms of communication are applicable, except, coming over with out warning because what you know of my beauty will be eluded by a bare-face, more than likely ashy skin, hair tied or all over my head, etc. However, if you don't hear from the person laid-up they've more than likely dosed off.

Kicking' it-> enjoying oneself whether alone or with a large group, laughter is usually heavily involved, sometimes music is included. Text messaging is the preferred communication because other wise I can't hear my phone and checking it or watching the screen is unacceptable.

Chillin'-> primarily solo or could be with up to three others. It's low key or more subtle. You can more that likely hold an applicable phone conversation.

Now!
Now that I've lined them out no one should be confused about what I mean and there's no code to break! Certainly no knuckle-headed "boy" should be questioning my interpretation further!
Thank you and Good day! (drops mic)
