My recollection is a little dusty but yes I believe "f*** his legs" would often follow a "SMASH EM", sometimes the lesser spotted "Smash em, the TWATS"
Obviously a ludicrously loud aggressive chant of ADAM EL ABD from one man at quiet moments during a game can't be forgotten also.
We went WSL...
I always enjoyed Big Phil greeting about 243 people on his way up to his seat after selling programmes. Famed.
Less a fan of the "f*** his legs" girl who would only scream very violent things.
Assuming you still mean the same place, I can't believe someone was determined to persistently stand...
