Even "PUAs" are often in the first category. Many guys getting into the pickup scene tend to start off using these canned one-liners and being insincere. Often they are really uncomfortable with talking to anyone, much less the opposite sex, so these canned openers and lines sort of help them build some initial confidence in some cases even though they're super cheesy - they are used as a crutch. But as they get more comfortable they sort of realize that using someone else's lines to seem like an interesting person isn't an actual replacement for being a genuinely interesting person. Some of these guys continue relying on the cheesy canned openers, but quite a few move on to actually learning more genuine communication skills and working on improving themselves in the long run, becoming genuinely interesting people to talk to.
