Fishin' Buddies 

Im the movie "Brokeback Mountain" the main charecters told their wives they were "fishin buddies" exept they were more. My friends and I use this to voice our suspicions when we think two guys may be getting it on...

"dude....they are pretty close"
"Well...yea, I think they're fishin' buddies"
