Matt Franklin

Topher Grace (yes, the actor who played Eddie in the Spiderman3) plays this character, Matt Franklin.
Matt Franklin works at a video store where on one fine day he saw his high school dream girl, Tori. When the conversation begins he throws a lie that he is working with Goldman Sachs (to impress her, obviously).

Tori then invites him and his friend to the weekend party. He went to the party to hit a chance on her. He is this insecure guy when Tori's boyfriend proposes her. Somehow they leave the current party and went to a different business party. His adrenalin helped him to impress the girl when he has to face an awkward discussion. They escape the crowded party and end up in neighbour's tarpaulin What happened finally is that they both were making love because of the character's sweetness and how comfortable he made Tori feel with him.
And then comes the TURTH.! he spokes out that he does not work with Goldman Sachs
He went back to the first party (where this girl was) and just like a "wanna be" hero he took a stupid challenge.What happened then? He got hurt, broke some laws, and made a fool of himself
Anyway, he ran back to Tori to give a last shot by asking her phone number.
After playing a little hard-to-get, Tori is actually impressed by Matt's sudden forwardness and rattles off her phone number

A simple character picked up from the life of a normal person.
If you find yourself in the similar initial situation, you know what to do now ;)
