  Armed with the extended semiclassical theory, we propose a Hall effect at
$EB$ order, particularly in Weyl semimetals (WSMs). We dub this effect the
in-plane magnetononlinear Hall effect (IMHE) since the Hall current and the
driving electric and magnetic fields are confined in the same plane. Similar to
the intrinsic anomalous Hall effect, the IMHE features an intrinsic nature
because it arises from the field-induced anomalous velocity $\vec{E} \times
\vec{\Omega}^B$, where $\vec{\Omega}^B$ is the Berry curvature induced by the
magnetic field through both minimal and Zeeman couplings. Employing the
low-energy effective Hamiltonian of WSMs, we reveal that the tilt of the Weyl
cone is the key to triggering this effect. Notably, we find that the IMHE can
survive even when the \textit{chiral anomaly} disappears because
$\vect{\Omega}^B$ (as the correction of the conventional Berry curvature) does
not contribute to the monopole charge. Furthermore, we elucidate the interplay
between minimal and Zeeman couplings for this effect. Finally, the experimental
strategy to detect the IMHE is discussed.
