Lyrics for Katy Perry – Last Friday Night (T.G.I.F.)

Verse 1
There’s a stranger in my bed,
There’s a pounding my head
Glitter all over the room
Pink flamingos in the pool
I smell like a minibar
DJ’s passed out in the yard
Barbie’s on the barbecue
There’s a hickie or a bruise

Hook
Pictures of last night
Eended up online
I’m screwed
Oh well
It’s a black top blur
But I’m pretty sure it ruled

D***

Chorus:
Last Friday night
Yeah we danced on tabletops
And we took too many shots
Think we kissed but I forgot

Last Friday night
Yeah we maxed our credit cards
And got kicked out of the bar
So we hit the boulevard

Last Friday night
We went streaking in the park
Skinny dipping in the dark
Then had a menage a trois
Last Friday night
Yeah I think we broke the law
Always say we’re gonna stop-op
Whoa-oh-oah

This Friday night
Do it all again
This Friday night
Do it all again

Verse 2:
Trying to connect the dots
Don’t know what to tell my boss
Think the city towed my car
Chandelier is on the floor
With my favorite party dress
Warrants out for my arrest
Think I need a ginger ale
That was such an epic fail

Hook
Pictures of last night
Ended up online
I’m screwed
Oh well
It’s a blacked out blur
But I’m pretty sure it ruled

D***

Chorus:
Last Friday night
Yeah we danced on table tops
And we took too many shots
Think we kissed but I forgot

Last Friday night
Yeah we maxed our credits card
And got kicked out of the bars
So we hit the boulevards

Last Friday night
We went streaking in the park
Skinny dipping int he dark
Then had a menage a trois
Yeah I think we broke the law
Always say we’re gonna stop-op
Oh whoa oh

This Friday night
Do it all again
Do it all again
This Friday night
Do it all again
Do it all again
This Friday night

T.G.I.F.
T.G.I.F.
T.G.I.F.
T.G.I.F.
T.G.I.F.
T.G.I.F.

Chorus:
Last Friday night
Yeah we danced on table tops
And we took too many shots
Think we kissed but I forgot

Last Friday night
Yeah we maxed our credit cards
And got kicked out of the bar
So we hit the boulevard

Last Friday night
We went streaking in the park
Skinny dipping in the dark
Then had a menage a trois

Last Friday night
Yeah I think we broke the law
Always say we’re gonna stop
Oh-whoa-oh
This Friday night
Do it all again

Perry revealed: “There’s nothing better than an impromptu dance party with my friends. My track Last Friday Night (T.G.I.F.) is a song about debauchery because I had one of those nights in Santa Barbara. We went out to this place called Wildcat and got crazy,” Perry admitted: “We had a couple of beers and danced until we died, then brought the party back to the hotel room.” She added: “Most of that song is actual truth, apart from the ménage à trois… unfortunately! But, yes, streaking in the park, that’s what we did, so we had to write a song about it the next day!”
