The sexual act of taking a fist full of lettuce it is shoved an agreed upon distance inside of the woman’svagina (opposite of hot lettuce) they then proceed to do the deed. After both are satisfied the man takes out the lettuce and is served as a family meal.
The cold bat is when one wakes up at 4 am in the morning and takes off all of their clothes (assuming that they do not sleep naked) then walks over to the bathroom to stroke their penis until it is erect, then proceeds to slap their penis onto the cold surface of the toilet.
I was challenged by my friend once to do a coldbat while my parents are sleeping.
