SDL
Short for 'Self Directed Learning'. It is a session well loved by medical students during their clinical years. During sessions like this, students have the freedom to either clerk patients, practise certain procedures, revise the textbooks, loiter around, sleep or go home early.
Clinical lecturer: I can't make it on time later, so I guess you all will have SDL.
Medical students: Yay!

Same Day Lay. This is when you meet a girl, then proceed to sleep with her in the same day of meeting her. Bonus points if you convince her to come back the next day for more!
That girl over there? Totally preformed a SDL on her.
