A fanbase name for the girls who LOVE the actor/singer Liz Gillies. They differ from her other fanbase "Gillians" in that they support not only her career, but her bangin body as well. You can tell a Gillian and a Lizbian apart by noticing that Lizbians talk about Liz Gillies' boobs more than or as much as they talk about her music while Gillians will only talk about her career. Gillians are boring. Lizbians are the fun, honest ones.
"I heard that Jessica is a Gillian."
"She's a Lizbian. Get your facts straight."
"Yeah. She wants to make out with Liz Gillies' face."
