圈饭

Meaning

"Zhěqí" (褶骑/Wrinkle Knights) is the collective name for Lu Han (ex-EXO) haters. Because Lu Han gets wrinkles all over his face when he smiles, his haters call themselves "Wrinkle Knights" (knights guarding Lu Han's wrinkles). However, after Lu Han announced his relationship with Guan Xiaotong and faded from the spotlight, he's no longer a top idol, so there's nothing left to guard and their numbers have decreased.
