whatcha doin'? 

It's a slang-y version of "What are you doing?", a question that expresses our interest in other person's recent or present actions.

- Hey Beepson, whatcha doin'?
- I'm just fiddlin' around. Nothin' special.

Whatchamacallit 

A word used when the actual name of the object in question will not come to mind. Very versatile but often very vague. It is derived from the phrase "what-you-may-call-it" which can be found in T. H. White's The Once and Future King.

Claire- "Hey, Adam, hand me the- the- you know, the whatchamacallit."

Adam- "The what?"

Whatadisaster 

the unpleasant bathroom experience endured by Whataburger customers after eating the Triple Meat Whataburger; this experience is purely due to the sheer volume of the meal, and not at all to do with any lack of quality on its brand's part

Marv: Let me guess: you've been having Whatadisaster all evening...?
