Mama Maligalig

What does maligalig mean? mi mama asked two salespeople and one cashier at that boxlike department store, having set her whims on this aqua teeshirt that said, Maligalig. One said pasaway, another said magulo, and later roommie said, magamo. She asked again, but isn't maligalig positive?

Perhaps maligalig is this.

Mama: Do you have a weighing scale?
V and A laugh: Bawal 'yan dito. It's anti-self-esteem.
Mama rolls eyes: It's not to measure your weight, it's to weigh luggage.
