He got a wrinkled up rock 'n' roll T-shirt on and a beanbag for a couch

He can hold his beer but he can't hold a job and he creeps your little sister out

When he flexes his muscle and he makes that Hooters girl on his right arm dance

Well he wants to be a star play air guitar someday in a heavy metal band

[Chorus] That's a red flag, that's a bad sign

That's a good bet somethin' ain't right

Hold on there, I wouldn't go there

If I was you

I ain't sayin' I'm a know-it-all

But something sure should have tipped you off

When he said, "Hey baby can I bum a couple bucks for gas,"

Yeah that's a red flag

You say this one's different cause he bought you flowers, a dozen every day for the week

He drives by your house every hour on the hour and writes you poetry

It's all about destiny, how it's meant to be, how it's written in the stars that shine

And he's talkin' love and kids and stuff, and you've only been out one time

That's a red flag, that's a bad sign

That's a good bet somethin' ain't right

Hold on there, I wouldn't go there

If I was you

I ain't sayin' I'm a know-it-all

But something sure should have tipped you off

When he called just to say "I called how come you didn't call me back?"

Yeah that's a red flag

Mama's boys and jocks and flirts, weirdos in speedos and plain old jerks

Hair-brained half-baked honky-tonk clowns with half a dozen girls in half a dozen towns

That's a red flag, bad sign

That's a good bet somethin' ain't right

Hold on there, I wouldn't go there

If I was you

I ain't sayin' I'm a know-it-all

But something sure should have tipped you off

Now I ain't sayin' I'm a know-it-all

But something sure should have tipped you off

When some guys says "My ex-old lady was a nag,"

Yeah that's a red flag

Yeah that's a red flag
