Gets on - or pretends to (5,3)

'or pretends to' is the definition.
I can't judge whether this definition defines the answer.

'gets' is the wordplay.
I cannot really see how this works, but
'gets' could be 'makes' ('make' can be a synonym of 'get') and 'makes' is present in the answer.
The remaining letters 'out' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'on' is the link.

Can you help me to learn more?
