la chain - When you’re too lazy to say L’chaim, so you just say 'la cha

When you’re too lazy to say L’chaim, so you just say 'la chain' and call it a day.

I was too tired to say L’chaim, so I just said 'la chain' and went to bed.

At the party, I said 'la chain' and left before anyone could correct me.

My friend tried to be fancy with L’chaim, I said 'la chain' and won the bet.
