Looking for something with one or two syllables and ideally a nationality to make the point - for example greek, french, Russian. Roll Hole or fat fuck are close. Arkansas (where rate is 40% of population is obese) would be appropriate but doesn't have the punch. Moby Dicked her is close but when you describe activities you don't say I greeked her or I russianed her - you say I did greek or I did Russian.
Need more brain storming.
