This is an unusual question, one which I believe has many answers. Depending on where you are standing yo mama could be right behind you all of the time, but sometimes you may not be able to know, for instance, if she is wearing a cloak rending her completely invisible to you. If this is the case, the only way for you to see her is if you have super powerful anti-invisi goggles, but if you don't have these, yo mama is still behind you even if you cannot see her.
That was the short answer, now here is the long answer:
Yes, yo mama is right behind you.
To get from the left to the right.
