I don't know why everybody who has seen a terrible movie immediately defines a word by that terrible movie. But before Jude Law took a crap all over the cinematic arts, an "alfie" was and always will be a "dog fart." Dog farts smell way worse than human farts. But dogs are better than humans because by-and-large they are much less harmful than humans are. So though their powers of farting assault our olfactory perceptions to the extreme, we have come up with a word that seems nice since the offense comes from the butts of Gods noblest creatures- the dog, K-9 Magee, man's best friend and companion. Hence an alfie is, was, and always will be what we call a dog fart.
Bandido alfied all over Alexandra!
Rosie laid an alfie, and I think it killed Alexandra!
Grandpa didn't fart, Fi-Fi alfied!
I put a butt plug in Max to keep the alfies at bay!
