Fattering 

When something should look flattering on you, but just makes you look fat. Fattering.

Used in a sentence - 'I'm not so sure about those pants... they're kind of fattering.'

Or when you're trying to give a compliment, but don't think it's deserved- 'Wow! Those pants are extremely fattering!'

Flattening the Curve 

Requesting someone to do a task or, for a commitment on a part-time basis while knowing the task or request has no set end date (or may well never end).

Fluttering poos 

Intermittent flatulence with loose stools that make an apparent flutter noise as they exit the rectum.

My youngest son Tommy had a case of the fluttering poos after we introduced eggs into his diet.
