  We explored the prospect of looking for a fermiophobic charged Higgs ($\hpm$)
via the same sign trilepton signal at the LHC. A fermiophobic scenario appears
in the type-I two Higgs doublet model where the coupling of the $\hpm$ with the
Standard Model fermions is inversely proportional to $\tb$. Almost all the
experimental searches rely on the fermionic production and decay of the charged
Higgs. Consequently, the limit on $\hpm$ for fermiophobic scenarios is
non-existent unless $\tb$ is small. We show that for a fermiophobic case, the
electroweak production of $\hpm$ is dominant for most of the parameter space.
Subsequent bosonic decay of the charged and neutral Higgses give rise to the
same sign trilepton signal. With a thorough phenomenological analysis, we
demonstrate that the same sign trilepton signal can be an excellent
complementary search to explore the high $\tb$ regions.
