While having sex with someone doggie style (from behind), one reaches forward and inserts their fingers into the corners of the reciever's mouth. One then pulls back on the corners of the reciever's mouth effectively creating a large smile resembling that of Ronald McDonald, the clown mascot for McDonalds.
Billy was doing Sarah last night and decided she needed to cheer up, so he gave her The Ronald McDonald. It didn't work!

Get the Ronald McDonald mug.
The main mascot of McDonald's Family Restaurants worldwide, Ronald is a mutant pedophile clown and an overall genetic fuck-up with his red puffy hair and his hideous facial features resembling a grown-up harlequin fetus. Was last seen singing with two naked children having their bath, who sang in turn "We Do Ron-Ron-Ron, We Do Ron-Ron".

This was part of an actual McDonald's commercial in Australia, no joke.

Rumored to be a close relative of Pennywise the Clown.
Kid: Moooooom! Ronald McDonald tickled my pee pee again.
