[Verse 1]
I took you home to meet my family
You asked if you could stay the night
Honestly I would not have minded, no
'Til you gave my sister the eye

[Verse 2]
We sat for dinner round the table
Big mumma's famous shepherd's pie (Big mumma)
I dropped my fork so went to find it, oh
Saw your hand on my sister's thigh

[Pre-Chorus]
Oh I
Don't know why

[Chorus]
I thought I was your mister
But you just want my sister
Oh, why have you done this to me, baby?
Now I know why you kissed her
When we played family twister
Oh, how awkward Christmas will be, for me

[Verse 3]
And now you're standing at the altar
You look so beautiful in white
But it's not me who's standing with ya, no
It's that backstabbing bitch sister of mine
