A phenomenon which only
occurs once an individual wears jeans. It is most commonly used
the lump or bulge which forms on the around the zipper/crotch area when sitting
down. Any attempt to 'squash' the said boner
may result in making the situation even more awkward, leading most to ignore
it and hope nobody else notices, much like when you pop a real boner
on the train and can't get it to go down.
