I;m pretty sure in the scene it was meant as a middle finger, but it works I guess.

People need to stop being so salty all the time

It was the middle finger. BB-8 just met him, doesn't trust him, and just found out he was lying about being part of the resistance.

Did you even watch the movie?

But this was when him and the bot where making a deal
did you watch themovie

No.

Google it

Literally everywhere has one or 2 people arguing but a majority rule says it's a thumbs up. Seriously, why in the hell would Disney ruin their image with a middle finger from a lovable character.

Its a Disney movie meant for kids so they would think "oh yea he gave a thumbs up"
while adults know its a middle finger based off plot details.

Disney has been doing more mature references like that for years.

******* Finn holds his thumb up next to him for an awkward ass amount of time
just to give the ultimate indication that it's a thumbs up

that's so the audience could confirm it, so they could match a thumbs up
to a lighter in with a similar shape
