Some guys call it Bull, since it is a Bull Chit way to permanently patch a flat roof, but it can be done to last a long time if done correctly.
It is also called Dope, Black-Jack, Plastic Roofing Cement and Buckets of Roofing Tar, but it is all the same.
In my region, we call the plastic roofing cement, Dope, and the mesh fabric, Minnie. To each their own.
Here are some instructions on how to do a Dope and Minnie patch.
