Dutch fiddler 

When two or men engaged in a sexual activity that involves a guy gripping his own penis and the partner takes the other mans arm and moves it in a masterbating motion.

Me and rob were doing the dutch fiddler last night when my mom walked in on us. I had my own dick and he was moving my arm so fast it was amazing.

Double Dutch Fiddle 

When you and a bro hold hands, with the intent to use those hands to finger a girl/boy.

Emmet: Remember when Tony and I held hands and fingered that chic?
Phil: Yeah. You gave her the ol’ Double Dutch Fiddle
