Perpendiculars
Parties called crushes, in which persons have to stand
almost stationary from the time of entering the suite of rooms to the
time of leaving them.
“The night before I duly attended my whether to three fashionable
crowds, `perpendiculars' is the best name for them, for there is seldom
more than standing room.” —Edna Lyali: Done van, chap. ix.
