the entire phrase "anak ka ng tipaklong" is just an expression - no real hard meaning... better than saying "s.o.b.!" you hear it most of the time among teenagers or street-smarts trying to brag on something; sometimes, some it is said out-of-exasperation, frustration or disbelief. It can be any other expression. The root word is "anak ng..." , tapos, dugtungan mo na lang kung ano gusto mo idugtong. Yun na! hope that helps!.. if not, "anak naman ng tipaklong" eh!
P.S. same thing with the word "naman"...
