Get ss to suggest adjective and noun pairs and write them in columns on the board:

ginger cat
rainy day
frothy coffee


Ss match unlikely combinations (WC-G-P) and have to explain why they work. This can be made into a points-based competition or fed mack to the class as mini presentations.

Ss could follow-up with short texts or mock dictionary definitions.
