slangtechnical
A person who uses slang, but sticks to the original meanings of the term as a slang term, and always 'corrects' people who use the slang term in a newer way.
Bobby uses the term "faggot" always to mean gay person and whenever somebody uses it for anything else he always corrects them and says "faggot means gay" even though faggot's literal definition is a bundle of sticks. He is so slangtechnical it is annoying.
