A sexual device, like a butt plug, used to loosen, open, relax and stimulate the anal sphincter muscle. Ideal for those into gaping.

Also may refer to a person that packs such a massive cock that they leave one’s anus pulverized and wide open after anal sex.
Rachel and I went to the adult shop last night and I bought her a 12x6 rectal dilator. She was gaping so good I was able to fist her.

Francisco took me home last night and we had sex for the first time. Let’s just say he’s a rectal dilator like no other. I’m sore.
