讨厌一切拿无知当个性的生物

Come on! I don't think they belong to post-90s language. Actually, they are wildly used internet words. if you go to some Chinese forums, like Tianya(天涯) or Mop(猫扑), you will see them everywhere. "槑" is the same as "呆", which means "dull". "啥米" or "虾米" means "what". "雷到" often used to express a feeling of shock. If you are shocked or amused by something, you can say that thing is "太雷人了". There are some other popular internet words, like "囧" , "华丽丽" and so on. I think it'd be great if you could master them so that you could better communicate with Chinese young people and also it'd be much easier for you to read some websites. lol. If you want to learn, I can help you. Cheers.

this type of sentence is usually by people who borned after 1990. it is difficult to learn if you are not native chinese speaker. some words, u can just read it as half. for example, 槑, it actually is the chinese word "呆" which means stupid or foolish. they double it to type 槑 is just they like the shape of 槑. but not all the word can read from half. for example, 啥米 is the word"什么"，also can be written as "虾米", means "what" . that type of words just can not read by half of them. and people like to type those words because they thought it sounds cute. actually most chinese people hate that type of words. and u dont have to learn those words.

i hate the man after 90s. 我讨厌90后的人。。。。。。。。。
