As for the "commonly said chat up lines", I can report some guys who have written somewhere their chat up lines and deal them out with unfailing repetition (even down to the last typo ), and sometimes even not noticing to whoom they have sent anything of that sort. Thus, I just received a message from a guy named "I am ALONEEEE" (and in my point of view likely to remain so ), which perfectly matched the same message sent 10 days ago  
"hi sweety girl. how are you ? ı kıss your lip. muaaa"
No hidden meaning there, but it just fits under the "common" part

oh I got ya :)) But Latvian roads are really special to some men Lina

No, it was like "I like your pic on the road! can you take a picture of me in the same place?" Like there are many similar roads all over the world and so many people that can take a picture of him. That's such a bad way to invite a girl on a date :DDD

think that one has something to do with nudity Lina :D

what does "Can you take a picture of me?" (said by a male) means? :D

I would love to see your house one day means i'd really like to sleep in the same bed as you
