look up any word, like thot:
To suck a penis like Phil Collins does.

The term "fellatio" (to perform oral sex on the penis), was in the past spelt "Phillatio". The word aquired it's meaning from the fact that Phil Collins sucks the dick. He later struck up a deal with the Oxford English dictionary to change the word, and keep it changed, for a price of $10 million per year. So, every time you buy a Phil Collins record, you are oppressing the english language and ridiculing the world's hard working lexicologists.
Phillatio is what Gary and Dave do best.
