Sample statements from a person with fortyitis:

"Man, in Rexdale, I saw a guy get thrown off a building. Body bounced five feet in the air."

"...Woke up the next day at home, and my ma says to me "why's a bootprint on my face?" I told her, "Ma, I got in a fight with a cop."

"This one time, I was takin' out the garbage, and I passed out in the corral. Woke up 40 minutes later.
