Marking 

I want to mark my lover to make sure no one touches them and for them to know they are already someone else’s. Usually used with your soulmate and often used In omegaverse.

Marking her was the best that anyone that wanted something to do with her can know she belongs to me. She was also very happy that I don’t want anyone else touching her.

Marking Out 

Getting really excited for something beyond logic or reason.

This is from an extension of the wrestling fan phrase and has grown into the modern lexicon. It usually comes from something you enjoyed in your childhood that you still enjoy into adulthood without logical reason.

"Dude, I totally am marking out for the RUSH concert"
"Man, when I saw Ozzy Osbourne... I started marking out"
"Theo Fleury is trying to make a come-back? I'm totally marking out dude!"

Marking Facebook Territory

After friends have a nasty fall out or a BF/GF break up and they race to comment or like a mutual friend's pictures/posts on facebook before each other in an effort to 'claim' the mutual friend and have them on their side of the break up/fall out.

Fuck, my bitch ex was Marking Facebook Territory on Sarah's profile picture before I could like the picture, now I can't comment or like Sarah's picture!
