(intro) B Ab Ebm C# (verso) B There's a stranger in my bed, Abm There's a pounding my head Ebm Glitter all over the room C# Pink flamingos in the pool B I smell like a minibar Abm DJ's passed out in the yard Ebm Barbie's on the barbeque C# There's a hickie or a bruise (pré-Refrão) B Pictures of last night Abm Eended up online Ebm I'm screwed C# Oh well B It's a black top blur Abm Ebm C# But I'm pretty sure it ruled (Refrão) B Last Friday night Abm Yeah we danced on tabletops Ebm And we took too many shots C# Think we kissed but I forgot B Last Friday night Abm Yeah we maxed our credit cards Ebm And got kicked out of the bar C# So we hit the boulevard B Last Friday night Abm We went streaking in the park Ebm Skinny dipping in the dark C# Then had a menage a trois B Last Friday night Abm Yeah I think we broke the law Ebm Always say we're gonna stop-op C# Whoa-oh-oah B This Friday night Abm Ebm C# Do it all again B This Friday night Abm Ebm C# Do it all again
