brain fark

When your brain over thinks about the opposite sex that you are attracted to and can never be with. They sometimes call you "friend" and "sister/brother". Knowing you will never have them, you continue to talk to them, making yourself feel better for that short time. After that moment has passed you, you cant get them out of your head, think of fairytales and you begin to question "why why why".

This can be associated to crushes.

I am sooo brain farked.

Men are all brain farks.

brain invasion

When you hold someone down, cover their mouth, and blow air into their nose so that it feels as if their brain is being "invaded". Fun way people annoy their younger siblings, along the lines of the wedgie or the wet willie.

When she held me down and gave me a brain invasion my head felt like it was going to explode.
