Does the sentence, “Lots of twilhearts went to the movie” make sense? If it does, what does it mean?

Solution 1:

I belive that what you heard was actually twi-hards, a portmanteau of Twilight and die-hards.

In the Urban Dictionary you can find twihard and twi-hard.

There is also a fan website at www.twihards.com, but they messed it up and you currently just get a directory listing, but the site can be found in the subfolder www.twihards.com/twihards.com/

Most media that have a lot of followers also get a slang term for the followers. Among the strongest followers we find:

• Wholigans for Doctor Who
• Trekkies/trekkers for Star Trek

Solution 2:

It is probably a neologism for Twilight fanboys, similar to the "potterheads" you also found in your Google search.

Solution 3:

Twilheart seems like a contraction of Twilight and Heart - meaning those who are obsessed or fanatic about Twilight including being part of Team Edward etc, it isn't a dictionary word.

Solution 4:

There is no mention of the portmanteau twilheart on urbandictionary (which is despite its deficiencies a good source for neologism and popular culture reference).

Searching for "names for twilight fans" I ran across the term Twi-Hards.

This article on MTV's site states:

"Twi-Hards is a nickname Michael Welch lovingly gave us on his blog," wrote TotalEclipse, defending the term. "There are some of us who think it's funny."

but most think it is derogatory, fan history wiki states

Twihards derogatory name for hardcore Twilight fans.

and urban dictionary has more. It is definitively not as derogatory as twitards.

Ah, after all this searching I took a better look at urban dictionary and got twihearts

TwiHeart refers to a person who is unconditionally and irrevocably obsessed and in love with the Twilight Saga.

(take into account that urban dictionary is not to be taken as authoritative on definitions, but it proves some people use it for Twilight Saga fans)
