Holy shit!  It has a name!  An actual name! 

When I was in college, every spring when trees and flowers were blooming I would notice a smell.  It came from certain trees.  Friends and I began to call this tree the “Cum Tree.”  During my senior year of college, I was blessed to have this beautiful, gorgeous tree right outside my bedroom window; however, I could never open the window because then my room would smell like…semen. 

What a beautiful tree.  What an interesting (?) smell.
