If you are new to football, you could be forgiven for seeking out a glossary of terms (like ours here) in order to help you understand what the hell people are talking about half the time.
For example, a team can sometimes be described as being "still on for the treble" or as having "won the treble" and if you aren't familiar, you might justifiably scratch your head wondering what it means.
In other cases, rows over semantics can break out among those who are aware of the meaning about what exactly a treble is - this is particularly prevalent among rival fan groups contesting the legitimacy of claims.
