Fuck yeah dude! 

Something one male, usually but not necessarily in the 15-45 age group, is wont to say to another male, when they are pleased, or are affirming their choice, feelings, experience, results, or the turn of events in general. 'Fuck' being an emphasiser. Occasionally spoken accidentally to a female, which becomes more comical in effect.

""hey, buddy, do you want to go on a road trip to a magical land?"
"Fuck yeah dude!"

"It's warm and the sun is out, what a day for summer fun"
"Fuck yeah, dude!"

""Let's be buds forever"
"Fuck yeah dude!"

*fist bumps and bro-hugs for all*
