I always found people who take pictures with the middle finger as a trashy gesture. I don’t and never know who they’re trying to tell off but it’s out of no where and just stupid. It doesn’t offend me, I just find it a pointless gesture and therefore - trashy.
‘Trashy’ was a word I’d formerly associated only with trailer parks, and wouldn’t have associated with Elon Musk, but some of the examples in this thread have expanded my view!
