What does "you'll end up needing a much bigger toothbrush" mean?
I'm rewatching the series premiere of Shameless (U.S.) and one line has always perplexed me.
Lip is talking to Steve after the latter gives him some medical 'advice' about a 'skeletal fact' and Lip replies,
Talk out of your ass with that much conviction and you'll end up needing a much bigger toothbrush; that's a[n] anal fact.
What on Earth does this quip mean?
Best Answer
It means that Steve would have to insert the toothbrush through his anus instead of inserting it into his mouth, so he'd need a really long handle. Not a really good metaphor to my way of thinking.
