I watched this movie years ago. All I can remember is one scene where an ugly man with bad teeth goes to the toilet and is bragging about how strong his stream is to a woman in the next room. He then comes out and starts touching her until she begs "f#%k me", then he stops and walks out. It is driving me crazy, please help!
The fellow taking the whiz was Willem Dafoe, bragging to Nicholas Cage's Girlfriend, Laura Dern that he must be hung well since his urine stream is strong and deep... Wild At Heart is the name of the movie I believe you're looking for. Hope that helps!
