Hippobottomus 

Having a hippobottomus means to showcase a rather excessive amount of flesh in the buttocks area of the body. It is an exceedingly insulting comment to declare one's buttocks a hippobottomus. It is commonly used in the clothing department of speech, as a sales assisstant may need to advertise clothing in the hippobottomus size, which is pants with 100x XL size. A hippobottomus is generally about 10000cm wide, and needs extra-stretchy clothes. Hippobottomus sizes of clothing might only be available from orders from online websites devoted to hippobottomus sizes of clothing. It is a major exaggeration to name one's buttocks a hippobottomus, but also is an extreme insult.

I am sorry, Ma'am, but we do not have these pants in the hippobottomus size.
