Morphology
The phrase literally lists two opposite actions ('suck' and 'blow'), so a learner who knows those words and 'and' can infer it refers to attempting to do two contradictory things at once. This compositional, contrastive logic is transparent and cross-linguistically accessible, making the idiomatic sense predictable for a B1 learner.
Etymology
The verb suck and blow comes from the simple image of trying to suck in and blow out with your mouth at the same time, which you can't do. So the phrase means 'to try to do two opposite things at once', for example trying to please both sides of an argument.
