To make up for my inability to remember how to make full sentences in Arabic anymore (putting aside the whole "I speak Modern Standard Arabic and everyone speaks a Lebanese dialect" dilemma for a second), I have been peppering my English and French with a couple of expressions I have learned or re-learned in the past two weeks.
Here are some ways to amuse Lebanese people immensely/have them compliment your Arabic and boost your ego temporarily until you remember they are just taking pity on your pathetic efforts.
