Tijuana Oil Change 

On a driveway (often covered with newspaper for easy clean-up), one person lets diarrhea drain from them while another person pours fresh diarrhea into his/her mouth, possibly through a funnel. A cooperative act.

Harvey went for a jog around the block to warm up before Brad helped him with his Tijuana Oil Change.
