The girl must have explosive diarrhea first. When having sex, get the girl on her back and left her legs above her, then have her shit up like a volcano and get it all over your face. Originated in Russian. Thus Russian Volcano
My girl explosive diarrhea, and we wanted to do some freaky shit in bed. So we decided to do the "Russian Volcano". That shit was foul.
