Code word: GALAXY

So the other night i wasn't feeling so well so I excused myself. I was gone for a while and when I came back John asked if I felt better. Long story short - H asked if I had "galaxy." Yea, I was just as confused.
"What?"
"Did you have galaxy?" very adamantly.
"H what do you mean did I have galaxy? John do you know what he's talking about?" He shakes his head.
"You know it's when you have pee poop." Trying not laugh.
Now for the weak at heart you may want to stop here.
He continues. "It's like you're peeing, but it's coming out of the place that you poop. You're poop is like pee - pee poop - galaxy." C looks on like "yea that's right"
"H that's called diarrhea."
"Oh."
Cut to 2 days later.
H stops playing. " I have to go to the bathroom."
"Do you have galaxy?"
both of us laugh.
So from now on when I used the word "galaxy" in public and it makes no sense at all, you will know what I mean.
