This phrase was used in the Vietnam war. The Vietnamese would camouflage themselves and hide in the trees and attack the Americans (which we 100% deserved.) the Americans were not used to this type of guerilla war fare and were very alarmed. They would yell “they’re in the trees” to warn the rest of their squad about the attack from above. Now this is a phrase that angsty teens say to express a sudden attack, or they just yell it out the window at unsuspecting pedestrians.

Get the They’re in the treesmug. Fuckers that tie themselves to trees that the logging companies planted. They are the reason why nobody can have nice cars because they "pollute". What they don't realize is that not enough people have them to make an impact. Not only that, they take SUV's and bury them, even though the battery acids leak and gas, further polluting the enviroment.
