We are looking at one guitar speaker cabinet that is 2 OHMs and we had only seen 4 or 8 OHM cabinets before.

This refers to the impedance of the speaker, and you are right that that value is unusual and most speakers are either 4 or 8 ohms. The rule is that the amp's output impedance should match the speaker impedance, but modern transistor-output amps will accept a wide range of speaker impedances. You should check the maual on the amp to see if it can be used with a 2-ohm speaker (assuming the amp and speaker are independent units). Some amps will overload if the speaker impedance is too low. The amp max output power goes up with lower speaker impedances (if it can accept that impedance).

It's a resistance rating. 2 ohm would be less resistance than 4 ohm, so you would not want to use a 4 ohm amplifier with a 2 ohm speaker cabinet; however, you could use a 2 ohm capable amplifier with either a 4 or 8 ohm speaker with no ill effects.
Speaker cabinets can be wired differently (Parallel or series) to change the ohm rating.
The bottom line is to try to match the ohm rating of the amplifier and speaker cabinet for best results.

An ohm is a resistance that produces a potential difference of one volt when a current of one ampere is flowing through it.

Ohms have nothing to do with resistance. It is a measure of impedence.
