Steph Curry Inks Up His Personal Tattoo Artist

We all knew Steph Curry's clutch under pressure ... but the dude just took it to a whole 'nother level ... getting behind the needle and inkin' up his own personal tattoo artist!!

The Golden State Warriors superstar met up with the guy behind his body art -- Zebra Tattoo artist Nino Lapid -- on Monday night ... giving him one hell of a birthday present ...

A PERMANENT AUTOGRAPH ON HIS LEG!!!

Lapid is the same guy commissioned for a private tat sesh for the Curry fam after the Warriors beat up on the Cavs last year ... so they're a really tight group.

It's not every day you get tatted by a 2-time NBA MVP ... but that's not all that went down last night -- Steph's wife, Ayesha, and teammate Damion Lee got in on the fun too!!

Luckily for Nino ... it looks like Steph's hand was as steady as his shot.
