a particularly shitty male haircut in which the sides cover the ears and the hair appears to be "snap on".
Cha Chi hadn't had a haircut in weeks. When he showed up it looked like he had lego hair.

When a person has hair that looks like a Lego hair-do. Example, when you go to the bathroom before bed, brush your teeth, snap off your Lego hair and set it on the counter for in the morning. The hair snaps off in the same manner that you would snap a Lego mans hair off. Lego Hairs are interchangeable and come in many sizes, shapes and colors. Lego hairs may be collected and stored to have many different Lego hairs on hand. Lego hairs can be washed under warm soap and water and they never lose their shape or color.
