DON'T BE A RANCH means not to be a flirty, strange person. If you are a Ranch, you will often wink or chin wave at random people at random times, mostly causing confusion. To be a Ranch is discouraged. A Ranch will do any of the following and more: wink, chin wave, double wink, touch butts of other people, wave in a flirtatious way, or all of the above (at once).
Rachel was randomly double winking at someone. Rachel's friend, Cindy, exclaimed "DON'T BE A RANCH!!"
