Keeping a backup crush warm in your DMs in case your main relationship faceplants.

means Maintaining a flirty backup connection on the side, just in case your primary relationship doesn't work out.

from From 'cushion,' the soft padded object that breaks a fall — rooted in Latin 'coxinum' (related to 'coxa,' hip, the thing you'd pad a seat for). The dating slang borrows the image directly: this person is the pillow you've quietly tucked under you in case the relationship chair collapses.
