As those with large corporation? (5)

I believe the answer is:

obese

I'm a little stuck... Click here to teach me more about this clue!

'with large corporation?' is the definition.
(corporation can humorously mean body fat)

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for obese that I've seen before include "Excessively fat" , "Very substantial" , "indecently large)" , "Morbidly overweight" , "Unhealthily fat and overweight" .)

I've seen this clue in The Sun.
