i aint gonna lie
A stupid way of saying you're going to say something, even though it's usually a lie. It's like when you're trying to sound smart but you're just clueless.
I aint gonna lie, I told my teacher I did my homework, but I didn't.
I aint gonna lie, I said I was going to get a good grade, but I failed.
I aint gonna lie, I told my friend I would come to the party, but I stayed home.
