  We construct $(p,q)$ string junction solutions suspended between both sphere
and AdS giant gravitons in $AdS_5\times S^5$. Our results extend easily to more
general half BPS geometries of LLM type. These carry angular momentum in the
directions of the worldvolume of the giant gravitons. We argue that these are
charged under a central extension of the supersymmetry algebra similar to the
one that has appeared in the works of Beisert for the ${\cal N}=4 $ spin chain.
We also argue that they are BPS with respect to this central extension. We show
that apart from some kinematical details, the junctions end up solving the same
minimization problem that appears in the Coulomb branch of ${\cal N}=4 $ SYM.
Their mass and shape is independent of the angular momentum $Q$ that the
junction carries.
