What it means
Tbh, short for to be honest, is the lead-in you drop before sharing a candid, often unfiltered opinion: tbh, I did not love it. It flags that frankness is coming, gently or bluntly.
Usage examples
"Tbh, I would rather stay in tonight."
"That remake was better than the original, tbh."
"Tbh, that fit looked way better in the pics."
"I was gonna go out, but tbh I'm shattered."
Where it comes from
An initialism of to be honest. It took off in early internet chatrooms, texting, and social media as a fast little honesty switch you could slap onto a message before saying what you really thought. It’s been common online since the 2000s and later spilled hard into everyday speech too.
