Go to Texas is when you have a wet dream. One may say that they had
a dream and "went to texas." Used as a code/
cover up when around older folks, women, etc.
Person 1:
Ah man, I had this dream that I went to Texas last night!!
Person 2 (knowing what's up): Oh yeah?
Person 3 (not knowing what's up): Why would you go to texas?
What'd you do there? Did you go to Houston? Austin?
Lubbock?
