McLolz 

Cheap Laughter, its when someone tells a bad joke or an overdone joke do get a few laughs. Like McDonalds, anything with Mc infront of it makes it bad and cheap...

McLolz can be used in context of a joke being told, or just if you feel like spicing up the LoL factor.

Man: Is that a bear?

Other Man: No! Thats my mom!

Man: McLolz!
