Primary school pupils have criticised an FA document which suggests girls could be encouraged into football by using bibs that "smell nice", having breaks so players can tweet and playing music during sessions.
Children at Lumley Junior School near Chester-le-Street, County Durham, did not believe the Considerations For Increasing Participation In Women And Girls Football paper was real when they read it during lessons about gender equality.
Among the advice were tips such as offering stamps and prizes for players to keep attending sessions, allowing girls to wear casual clothing and using colourful bibs - but "make sure they are clean and smell nice".
The document also suggested some beginners might be put off by being hit by a heavy ball, so coaches should consider using smaller ones.
Girls should be allowed to play music during football sessions, the paper suggested, and their games should be indoors in the winter.
One tip which particularly angered the Lumley pupils was "Allow girls the time to check their phones within a session or incorporate a Twitter break so participants can tweet about the session".
The year five and six pupils were encouraged to respond to the FA as part of a writing project and Nancy, aged 10, gave the governing body both barrels.
She wrote: "I am absolutely astonished that you have the nerve to write all of that absolute rubbish about women and girls playing football."
She told the FA chief Martin Glenn: "Your tone of voice sounds as though you think we are brainless baby Barbies!"
Fellow year six pupil Grace wrote: "We are not fussy about the smell of our bibs - would you be? And we are not afraid to get hit by a ball so why would we need light ones; in case we break a nail?"
Deputy head Carol Hughes said the pupils, girls and boys, were struck by the implied sexism of the document. "We kept thinking, what would they write for boys?" she said.
The school runs a girls' football team and children of both sexes play keenly-fought games during lunchtime. Hughes sent off the pupils' letters at the end of November but has not yet had a reply from the FA. She said: "I am incredibly proud of them, I just hope they get a response soon."
