New Wonder Woman Gal Gadot -- Super Wedgie [PHOTO]

Exclusive Pick

The new Wonder Woman in Ben Affleck's upcoming "Batman vs. Superman" flick really could've used her golden lasso over the weekend ... to help extract a major wedgie from her butt.

Gal Gadot -- famous for her role as Gisele in the "Fast and the Furious" movies -- was out for a bike ride Sunday in Tel Aviv ... when she had to pick that scrunch in her bunch.

Lex Luthor, you've been warned -- this Wonder Woman goes deep.
