slang term for the word bollocks which can also be spelt bollox. Bollo then comes from the fact that an 'x' at the end of the word should be silent, for example the word gateaux.
Bollo is an anthropomorphic ape who has been portrayed as inept yet immensely strong on the BBC show The Mighty Boosh. He is also Naboo's familiar, plays the drums and DJs at Fabric. His catchphrase is "I've got a bad feeling about this...".
