completely and utterly useless phrase people up north use in the place of ya'll. it means you guys, but they just have to be stupid and (besides not using the much simpler phrase ya'll) add -es to the phrase "you guys". As I have said many times with great wisdomosity, ya'll is much simplier to say.
Hey are you guyses going to the movie?
The rube form of the possessive case of you used as an attributive adjective.
Man, I'm hungry. Where is you guyses trough?
