One who can not retain information due to a lack of a properly sized penis.

Lore- It's said that these people think with their second head because their actual head is smoother than a bald man's head fresh out of a wax job.

A person diagnosed with SDML is known to forget information attained in the last 10 minutes. The time in which someone loses information often varies depending on how small the penis is. People with smaller penises usually ranging from just tip to 2 inches have shown that they forget way more frequently and will have to ask you to repeat what you said numerous times.

SIDE EFFECTS- No Bitches and possibly no friends
EARLY SIGNS- You can catch early signs of SDML when you measure your penis and it's smaller than 4 inches.
TREATMENTS- None (sorry to break it to ya, hope you got mone cause you ain't pulling shit)
