Blorp

In 1985 I started making the sound "blorp" to emphasize the presence of an obese person.

I would pocket air in both cheeks with my mouth closed, and force a hard 'B' out of my mouth, popping my lips, at the beginning of the word, and forcing a hard 'P' at the end of the word 'blorp'.

I am unaware of any use of this word before 1985. So, I consider this, the primary definition of the word 'blorp'.

Blorp would be used when an obese person sits down, near you, walks by you, or is even just standing by you. No other words are needed. Just:

"BLORP"
