Lesbian Astronomy
Noun: Generic term used to describe intellectually bankrupt, useless college courses, taught by defensive, hostile and unqualified professors that exist only because they are politically correct and students are forced to take them. Comparable to Underwater Basket Weaving, except that is mandatory and the grading is brutal.
Poor Jin - he had A's in Calculus, Organic Chemistry, Applied Physics, and Programming for Artificial Intelligence, and the poor bastard was lucky to get a C-plus in his required bullshit course - Lesbian Astronomy, or whatever.
