a relative measure of a person's ability to use and understand a language: usually suggests an evolved mastery of not only what a word means, but also the connotations that are related to it
On a particularly balmy day in Moscow, I exclaimed, "ya tyoply," or "I'm hot." If I were fluent in Russian, I would have known that "ya tyoply" suggests that "I am horny," and that "mne teplo," or literally "it is hot to me," is more appropriate.
A word used for emphasis. Makes you sound kinda "cheerleaderish" when you use it.
"that minger is fluent ew"
"that guy is a fluent hottie."
