I just found out that there is a trashcore (?) band called Obscene Gesture.
Don’t they look all tough and mean? (source)
And then that menacing gesture that is just ‘disgusting to the senses’, and/or ‘repulsive by reason of crass disregard of moral or ethical principles’.
These men-boys will have to watch out for the US laws on obscenity.
A final note: should their music be considered one giant musical gesture?
