plastic fan
n.— «I can’t believe the amount of complaints I’ve heard this morning on various sporting broadcasts about the attendance at last night’s Chelsea-Rosenborg match. What’s the big deal? Surely these people know that Chelsea are not one of the traditionally best supported clubs in the country, so why go on and on about them having too many “plastic” fans, etc?» —“Chelsea & ‘Plastic Fans’” by MrH Vitalfootball.co.uk (United Kingdom) Sept. 19, 2007.
