My face to people who think that your about to ask them for something. Then they quickly let you know that they are not available.

Example:Where you going?

Answer: I'm not driving, I'm taking the subway to the city.

Reply:Ok, when you get back grab me a dutch so we can smoke.

Example 2: Hey I'm coming to Montana next week.

Answer: My house is a mess and aren't you allergic to cats?

Reply: Yeah....I already booked a hotel for the week, thanks.
