Someone who you would go on a roller coaster with in order to keep you company. Without a roller coaster buddy, it would have to be pretty embarrassing to be the only one in your row on the coaster train. It is a known fact that single people want roller coaster buddies.
Joey: Will you be my coaster buddy?
Rachel: Sure, I'll keep you company on the roller coaster.

While dating, when one person seems to be ghosting the other but then miraculously reappears once again after the other has come to terms with being the ghostee and is already over it. They often make a routine of it, thus causing an up and down roller coaster effect.
Friend #1: girrrl did you ever hear from that dude again after he ghosted you?
Friend #2: ya! He sent me a message asking how I’m doing. I’m not gonna reply. I ain’t out here to ride the ghoster coaster.

A towel, or other absorbent material, used to protect a bed, bench, chair, etc., from the residue moisture left over on one's posterior after a shower, bath, or swim. The towel acts much like a coaster that is used to protect furniture, except this time it's protecting the bed from your wet butt.
"Can't you please use a butt coaster" said Jean, after I got our bed wet by sitting directly on it after coming out of the shower.

The feeling that you're still flying after you ride a coaster, or even after leaving the amusement park.
Similar to a rollergasm.
Person A: Dude, I just rode the Intimidator. I swear, I'm on a coaster high.
Person B: I know, man, I got that even after leaving the park.
