Turning someone down

Turning someone down
I’m not interested.
Sorry, you’re not my type
I’m seeing someone else.
I’m with someone
I have other plans.
I’ve got something going on.
Something suddenly came up.
I have to wash my hair.
My calendar is full.
You’re not my type.
Not if you were the last man on earth.(rude)
You must be joking.(rude)
I don’t feel up to it.
I have a headache.
Please.(with a disgusted tone of  voice)
