The most widely accepted meaning of the word BoXeR* is someone who gets annoyed when they join a public server and get raped by n00bs.
In
pure frustration you can observe this specimen join a server, get totally owned by other freezetagers, at which point he
will utter one of his catch phrases like "fckn n00bs", "take you all on at osp" or "
ffs spam" and then promptly disconnect.
The above phrases literally traslate to such things as: 'Im leaving because its my time of the month and I cant handle loosing' or perhaps: 'Your more skilled than me, but
Id rather quit than admit it'.
