Feed The Monkey refers to a fuelling of desire.

Usually this desire is something one doesnt want to do, but is addicted to it because of the way it makes him/her feel about himself/herself.. like getting high.. or playing poker.. or going to a strip club.

Scientifically speaking, 'feeding the monkey' is feeding the dopamine gland in the brain..
'I don't think you should break up with her just because she gives lapdances to your family members in fancy restaurants.. She's gotto feed the monkey..
