if you "like" something of another persons, chances are they'll "like" something you post.
but if you want a real tip for facebook:
message 2 single girls (both at least 10minutes apart) on your facebook chat and ask them if they could help you out with something, then ask them if they could write something teasing on your wall to make a girl you like jealous. if they ask what just tell them to post somethin goofy like "hey you! we need to hang out soon! party? i think yes
" so far all my girl friends on facebook have done that, i ask a different 2 every week to! this is social proof up the ass! girls like what other girls like. and if girls see 20 girls writing teasing things on your wall...others will come. gotta put this in my journal next week. lol.
