Also known as a stalker, a queef-a-saurus rex is an ex-girlfriend who won't leave you alone even after you have clearly shown an extreme lack of interest. She is famous for farting out of her vagina which sound like the roar of a dangerous predator.
Oh my god that queef-a-saurus rex won't stop calling me! She used to force me to go down on her and one time she queefed so hard she parted my hair! I've lost my sense of sight and smell not to mention being scarred for life!
