heading for a spreading
Just like 'cruising for a bruising'. Means you're in for trouble.
If you don't tidy your room you're heading for a spreading!
head spread
When a person's head widens as they age. This is particularly true with males. (Alec Bakdwin, Zac Efron, Matthew Perry are a few examples)
Matthew Perry had serious head spread between season 1 and the final season of Friends.
