Kanye West Fist Bumps Fan Who Calls Him 'Amazing Father'

Kanye West will give you a fist bump if you call him an "amazing father" ... as one fan found out while Yeezy was grabbing some ice cream.

The bizarre interaction went down Thursday in Calabasas, where Ye hit up an ice cream shop after a doctor's visit.

Kanye's licking his ice cream cone and answering a paparazzi's question about the death of fashion icon Andre Leon Talley ... when suddenly someone comes up and praises Kanye's father skills.

Ye perks up and gives the dude a fist bump, telling him he loves the praise and appreciates the recognition.

Kanye then gets behind the wheel of his whip ... which turns out to be a minivan!!!

Seems he's got plenty of room for North, Psalm, Saint and Chicago to ride in the back.
