lazy blueberry

(ley-zee-bloo-ber-ee): a "lazy blueberry" is the name for a testicle that has fallen asleep during any kind of rigorous activity. The ball falls asleep because blood rushes from it to your extremities. This most often occurs during the act of masturbating and sometimes while swimming or playing basketball. This almost never happens while using the restroom.

Yesterday I got a lazy blueberry while sprinting to the mail box. My porn didn't arrive.
