S, short for suck and D, short for dick. Literally means, to suck on (or off) the male private part belonging to the current day. More commonly, it is an metaphorical expression that defines ones disinterest toward the necessary tasks or obligations (work, school, studying, hw) one must complete in the day afoot. Usually a mental note to self, as opposed to a statement.
Everyday I wake up to my crappy life, with my crappy dead end job, drink a cup of crappy bobo brand coffee and sigh (thinking, time to S today's D)
