Porn tree
During the heat of the summer or, occasionally, those rare cold moments in Las Vegas when undesirable conditions happen outside, the local porn vendors forego standing outside pushing their little cards and instead cram their literature into all the helpless limbs of the local foliage,then proceed to take refuge inside the climate controlled goodness. Thus creating the "porn tree".
"man it's hot out here".
"ya, but at least the porn trees are in full bloom".
