Are there any things people like to do when there is a big lul in a conversation? because I absoloutly refuse to start asking boring questions like asking how their day was, etc.

Sometimes I just say random offbeat funny shit, depending on the character of the person I am talking to, and it usually extends the conversation with a few laughs or some sarcastic jokes, or we go off on a crazy humerous tangent for a good long time, but sometimes I just feel like too much of an attention whore when I do that.

You don't always have to be talking. If you demonstrated a significant amount of value she will talk to you again and make every effort to "reignite the conversation"...
However when you first meet a chick there is the exception of the 90/10 rule, which states that you should do most of the talking when you first meet someone. In these situations when I run out of material, I simply stare at the target and give an ambiguous cheeky smirk, this is always useful tool in setting a playful tone with elements of mystery...The target will say something like: What!? ...Reply: Nothing :p! / Hmm your a character!...Tell me when you were a kid, what did you want to be when you grew up?-And don't say princess!

Not bad, this is good stuff.

Thanx bro
