Kanye West & Bianca Censori Greeted with F-Word in Paris ... Mob Chants 'F*** Adidas'!!!

Kanye West and Bianca Censori are getting full-throated support in their fight against Adidas ... as a Paris Fashion Week crowd rallies for their cause.

As Ye and Bianca left The Ritz Wednesday for a lunch break, they were quickly swarmed by fans and photogs outside the hotel ... some of whom began chanting "F*** Adidas" in unison.

The profane chant clearly got a rise out of the couple as they both cracked smiles of approval -- well, it seems like Ye was smiling. Hard to tell, really, with the full mask over his face and head!

Kanye was especially pumped up ... he encouraged the crowd to chant louder, and grabbed an autograph seeker's copy of his 2010 classic album "My Beautiful Dark Twisted Fantasy" and signed the words "F*** ADIDAS" in black marker!!!

Earlier in the week, Kanye went hard at Adidas, accusing them of raping his fashion sense by selling Yeezy sneakers he never greenlit.

Spicy words, but his fans -- at least in Paris -- are riding with him!!!

The head-turning couple continues pushing boundaries at Fashion Week events -- Bianca popped out Tuesday night basically bottomless with only sheer pantyhose to cover her hoo-ha.

They definitely got some folks in Paris going gorillas this week!
