a sexual act in which a male is engaging in sexual intercourse with a female on a beach, and then takes his dick out and rolls it around on the sand so it can resemble a churro... very useful if the female likes to have sex with sandpaper
Billy: dude i fucked her then busted the churro!
Zak: no way dude no fuckin' way dude... no way!
Billy: haha yeah and now she has a sandbox pussy!
Zak: no way dude no fuckin' way dude... no way!

when having sex at the beach, you quickly dip your penis in the sand and prepare to surprise your partner with a real burn.
