A private all-boys school in Dallas, Texas that is exclusively for gentlemen with epic swagger. The ladies lust for the dapper physique of the Marksmen who attend. To get into St. Marks, one must have a 8+ inch penis, which is checked exclusively by the headmaster.

*Daquan shows his penis*
Daquan: You’se is damn straight!
