Girls, Is there really a good way to approach in a bar or club without being a total creep?

The first few words are the most important thing. When guys come up 2 me in a bar I usually never talk to them 4 that long. The usually way is can I buy you a drink and I totally say yes but once got the drink I don't care no more as I just wanna party with my friends. Ur first few lines have 2 get the girl interested. Cheesy chat up lines are funny and good 2 start a girl laughin but not 4 the right reasons. Personally it depends on the girl but if a guy wanted 2 come up 2 me I would tell him come over and talk 2 my friends aswell start a conversation with the people I'm with and make them laugh then focus on me after if that makes sense

just walk up and be like hi I'm so and so what's your name and take it friom there
