决战逗比之巅
[jué zhàn dòu bĭ zhī diān]
'Ultimate battle at the peak of ridiculousness'. 'Dou Bi' has multiple meanings here - firstly, it means silly or funny (usually lovable); and secondly, in certain contexts especially online, it can be a rude way to say homosexual males. But overall, this internet slang is often light-hearted, expressing determination to participate in some competition full of fun and laughs.
