Note: My question is in regards to everytime I fill my "lighter". Also, can it cause frostbite?

Depends on the temperature. I tell you, if it's burning, it's NOT cold :).
It's metal container feels colder than the surroundings, that's because of the metal properties; it leads away the warmth of your finger speedily (/right away). That's because metal conducts warmth easily.
It doesn't matter WHAT you pack with metal, if you let it come to room temperature, and then touch the metal, it'll feel colder than it's surroundings.
Because your body generally is approx. 37.6C, and the room temperature is approx. 20C, together with forementioned properties, metal in your home feels cold.

Its cold because the butane is a liquid and it wants to be a gas. so it absorbs the heat from the atmosphere and your hand, thus leaving your hand cold. To cause frostbite it would take alot of heat to be absorbed.

Butane, also called n-butane, is the unbranched alkane with four carbon atoms, CH3CH2CH2CH3
liquid n-butane has a higher boiling point (â0.6°C) at atmospheric pressure than that of liquid isobutane (â10.2°C).
since they r volatile at room temperature ,they absorb heat from your skin( if you are touching it) and evaporate, making you feel cold.
