I need help trying to figure this out

So this user on my PSN has tasked anyone with trying to figure out what her username is abbreviated stands for. It’s JIMLMSMA. I have tried hard. I think parts of it are “is” “my” and so forth.

Just start throwing out random phrases with these letters, and we can make a game out of it.

She’s Canadian and I have found other users by this name, so maybe it’s of Canadian origin.

CASE CLOSED. I figured it out. But for the sake of others Googling it from my PSN and hers I will not tell you guys. Topic closed.
