When you smell check a girl and lift the blanket like a dutch oven and her vagina smells ratchet. The smell smacks you in the face like a dutch oven fart. Thats a "ratchet oven".
Smell check, then lift the blankets and smack in your face like a dutch oven...
"Yo B... Get your dirty ratchet vagina out of my bed!"
Example- (conversation between friends)
Boy- "Yea one time i messed with this stripper chic, i did the smell check. I got all comfy under my covers and woosh it hit me in the face smelling like shit box"
Girl- "ewe, now thats what you call a ratchet oven"
Boy- "LMAO, Damn right, I told that nasty b*tch to get her dirty self out of my bed"
Girl- "Dont let that happen again"
