You mean a universe and a half to me

So it's, in my opinion, a better way to say: "you mean the world to me" because the universe is infinitely greater, bigger, and stronger than just the world. "And a half" is the basic meaning of it, where in this case, you'd use it as a way to say that something is very good, large, etc. ( in a positive sense, of course).

Half a Rob

Phrase, Slang, Twitter Joke, Patreon Blunder
ˈhæf ə ˈɹɑb
1. While wearing underwear (with or without pants), one mistakenly believes they have to pass gas, but it is actually a bowl movement about to pass through the anus. Instead of the anus relinquishing the excrement, it is pulled back into the body causing a surprised reaction from the person. This may or may not result in a mark on the person's underwear.
2. When you think you need to fart but you suck it back in as the turtle kisses your underwear.

I have a tummy ache and pulled a half a rob so I had to run to the bathroom.

Two and a half men

A gay threescore where one member is either very short or a midget.

I was smashed last night. Way too many Jager shots. I woke up next to a midget and a really good looking guy. Two and a half Men. You can find d it on Urban Dictionary. I just never imagined I'd experience one.
