The term "come on lads" could be considered offensive and should be avoided by players, a football association claims.
Berks and Bucks FA instead suggested in its inclusive language guide published this week that gender neutral phrases like "come on team" should be used.
It advised players to "avoid gendered language and assumptions".
The association also discouraged saying "linesman", advising that "assistant referee" was a more "modern, inclusive term".
The guide added that the word "guys" should be avoided in team warm-up chats, instead recommending that "everyone" is said instead.
An introduction to the guide reads: "Language sets the tone.
"It shows whether someone belongs or feels excluded, whether they stay in the game or walk away.”
Callum Salhotra, Community and Inclusion Manager and Berks and Bucks FA, said: "Football has the power to unite communities and change lives.

"But for that to happen, everyone must feel like they belong.
"Language is at the heart of that — it can break down barriers or build them up.
"This guide will help us all take simple but meaningful steps to ensure our game is inclusive, respectful, and welcoming to everyone."
The 26-page document suggested examples of other inclusive language regarding race, sexual orientation and religion.
Sir John Hayes, chairman of the Common Sense group of Conservative MPs, described the guidance as "deeply worrying".
According to The Telegraph, he said: "At best, this is daft. At worst this is sinister."
“The association should get on with helping clubs to do the best they can for all those who want to be involved in football to have their chance regardless of where they start," Sir John added.
“So my message to young, current and aspiring footballers is come on lads."
