A sexual act in which you deficate in your fowl gym sock and tie the top. Then during intercourse you whip out the feces filled sock and proceed to beat her for six to seven minutes until the feces seeps through the sock. You then untie it and pour the contents onto her/him.
My bitch was giving me head then I "gym socked" her so good.
