from wiki:
I have read that Larry McMurty purposely used incorrect Latin because of his characters(Gus wrote the phrase on the sign). The scrambled meaning of the phrase translates to a "grape changes color [i.e., ripens] when it sees [another] grape." This would explain why Gus says "you ride with an outlaw you die with an outlaw" when they catch Jake with the horse thieves, meaning that you show your true colors in the presence of others.
