why the fuck u talking to her if she ugly in the first place?
if she pretty but asks if she looks good - low self esteem, play on that to get in her pants.
if she knows she's hot - she won't ask your opinion unless she desperately wants your dick and wants to use that as a way of getting in your pants.
lmaoJust tell all future girls you meet that your name is Ruck and every once in awhile change Ruck to fuck and it'll subconsciously make her want to fuck.
EXAMPLE:
Girl: what's your name?
You: Fuck
Girl: What did you say?!
You: Ruck
Girl: ohh... is it hot in here?! let's get out of here
You: I have air conditioning at my place to cool you down
Girl: yessssssssss
The rest is up to you. But this is a very solid game plan. 100% bullet-proof.
