Bitty baby

Something so small that it'd be bitty even for a tiny baby. Too wee to make a difference, more of an insult than a sincere offer. Somewhat offensive to even have somebody offer you a bitty baby anything, waste of time even considering it! Thanks for nothing, literally, nothing.

That bitty baby bottle of Rhum is for who? Us? Me? Maybe it's enough for a teething infant but wtf you expect me to do with that??!

Stummy

What a person caught somewhere between adulthood and childhood calls their abdomen. The grown-up wants to sound respectable but the inner child prefers cutsie terms for parts of the body. The inner battle starts with the adult taking charge, but the kid butts in in time to put their two cents in. Result - stomach + tummy = stummy

I must be getting hungry, my stummy just growled!
