The stakes are extremely high for the Phoenix Suns as they face off against the Milwaukee Bucks in Game 6 of the NBA Finals on Tuesday. A win for the Suns extends the series to a seventh and final game, while a loss will mark a heartbreaking end to what has been a tremendous campaign for them.

With everything on the line for the Suns, a random superfan decided to show his full support to his beloved team by posting an epic billboard near downtown Milwaukee. It didn't take long before Bucks fans took notice of the audacious move, and unsurprisingly, they weren't very happy about it:

Talk about a slap in the face, right? Whoever was behind this epic diss not only knows how to get in the head of his opponents but clearly, he or she is also very much willing to spend a whole lot of money to get this done.

You may have noticed that there's a small logo at the bottom left corner of the billboard which reads “Warner Angle.” A quick Google search produced a link to a Phoenix-based real estate law firm called Warner Angle Hallam Jackson & Foremark PLC. This firm appears to be the mastermind behind this shade-throwing move, which is clearly an impressive marketing ploy for them.

If this billboard goes viral then Suns fans are certainly going to appreciate Warner Angle's effort to blatantly broadcast their fandom right smack in the middle of enemy territory. Bucks supporters, on the other hand, are definitely going to have a different reaction over this.
