Wee guy 

Wee guy, or wee guy mentality, is a slang term in Scotland used to refer to someone(s) who demonstrates toxic or immature behaviour (that is commonly found in young teens) when they are wrong or inferior to others. They often display these toxic traits in situations where they (for once) are correct or feel superior to others. Very similar to wee man complex.
The origin of the term comes from young teens (hence “wee”) who often demonstrate said toxic/immature behaviours. Thus the term is, in essence, an insult, referring to someone as having the mentality of a young child.
