Wee-k-eh-N-D B-awl-L-s ; Weekend Balls is a common cause and effect of a hard week where once the weekend comes, the subject (person with balls) wants to relax and doesn't shower for the entire weekend and the resulting smell of their nether regions can only be described as "Weekend Balls".
OH MY GOD, bae, I just got a strong wiff of your weekend balls. PLEASE SHOWER.
