Personally, as much as I love metal, tapping died 15 years ago....but I can understand that lovers of spandex rock may still see its benefits.
For the "cool effect", learn how to solo in jazz or blues...and if you want to pull a lady, sit in a corner and play a little well-oiled classical...its extremely impressive when played well. Oh yeah...and don't forget to put the guitar down when people start to come near...the bashful thing only gets them wanting more
lol. trust me it works
