Definition: "Silly"

This is a charade - multiple word parts are joined together to form the answer. Look for words or phrases that can be transformed and then combined.

"Rejected" is a reversal indicator. Take "positions" (as a verb, meaning 'places' or 'puts'), reverse it, then add "I would" in its contracted form.

Answer: STUPID | "Positions" gives PUTS, which when "rejected" (reversed) becomes STUP. Add "I would" contracted as I'D to get STUP + I'D = STUPID.
