look up any word, like blumpkin:
When one performs the act of pulling his ballsack upwards whilst tucking his penis in between his legs, giving the illusion that one only has testicles but no penis, thus the lonely peach
Joe: Shit bro where the fuck is your dick?!?! You lonely peaching?
Rick: No. I have a disfigurement. Thanks for making me feel self concious. Dick
Joe: Oh im so sorry man...
Rick: Ahhhhhh got you im lonely peaching!

That is how the lonely peach works.
