When a friend uses other friends as a buffer to flirt with a girl under the disguise of a group text, group email or social situation. Kind of like how a gay man can use a woman as cover.
"Hey, are you on that group text message that Ben sent out?"

"Yeah, he just included us so it didn't seem like he was hitting on Jen, we're his flirt curtains"
