The meaning of "copped a def un"

[only_me]

I heard this term used when i was very young. I do not have a clue what it means? Has anyone ever heard this saying or know what it means?

[nikki-red]

I always though it meant something like 'pretended not to hear'.

[Joto]

I think nikki's right, it's talking to someone who doesn't listen or doesn't want to.

Love the old sayings.
