  The breakdown of the celebrated Fermi liquid theory in the strange metal
phase is the central enigma of correlated quantum matter. Motivated by recent
experiments reporting short-lived carriers, along with the ubiquitous
observations of modulated excitations in the phase diagram of cuprates, we
propose a model for this phase. We introduce bosons emerging from the remnants
of a pair density wave as additional current carriers in the strange metal
phase. These bosonic excitations are finite momentum Cooper pairs and thus
carry twice the electronic charge, and its net spin can either be zero or one
arising from the two spin-$1/2$ electrons. We show that such a model can
capture the famous linear relationship of resistivity with temperature and
manifests the Drude form of ac-conductivity with a Planckian dissipation rate.
Furthermore, such bosons are incoherent and hence do not contribute to the Hall
conductivity. The bosons emerging from the electron pairs of spin-triplet
symmetry also reproduce the recently observed linear in-field magnetoresistance
