Molly McButter 

The act of a man having sex with a woman by repeatedly stroking his penis under her armpit. The term is similar to armpit sex, the armpit fuck, or dick in a headlock. However, it differentiates itself through the use of household items such as butter, margarine or cream as a lubricant to entice the woman to lick the penis as it protrudes from her armpit.

Man, I got a mean burn in my armpit from a Molly McButter last night.

I had to de-grease my penis after giving some Molly McButter to my old lady.

Molly McButter 

A plain jane type female, often associated with the term 'white girl' -- though not always, generally at least loosely associated with a sorority.

I can't picture that Molly McButter getting down.

I'm not down for no Molly McButters.

Molly McButtersquash 

When the female partner mounts her male counterpart from the cowgirl possition, taking the load, then jumping up for the face ride, while pushing out the marshmellows....

Brenda rode me so hard, I couldn't resist giving her my fluffernutter, but regretted it after she gave me the Molly Mcbuttersquash facial.
