Quite similar to button the mutton (i.e., to give a hand- or blowjob), however, stutton the tutton is generally much rougher and only performed by the most willing of partners. Therefore it is common for one to take serious offense when asked to stutton the tutton if they are unwilling.
-I asked her to stutton my tutton on the first date and she slapped me.
-Dude, you don't stutton the tutton EVER on the first date if you want to be a righteous dude.
-Dude, so I asked to button the mutton but she went all the way for a stutton!
