Sometimes people say "as if" which is short for "as if I ever would" which itself is a short form. I like the example from Quora: "He asked me to pay for his lunch, as if (I ever would (pay for his lunch)).” It means I would never pay for his lunch but he asked me to pay as if I would. Again, he's wrong, I won't pay. lol :) https://www.quora.com/What-does-%E2%80%9Cas-if%E2%80%9D-mean-in-this-sentence-%E2%80%9CHe-asked-me-to-pay-for-his-lunch-as-if%E2%80%9D
