Exactly

Pushing is anytime your minion wave has higher pressure than the opposing. Most players think pushing is when your killing waves in under 3 seconds flat...Not really. Pushing is exactly that, anytime your wave has more pressure than the enemy wave. If your wave is moving closer to their side each wave then your pushing. If you properly freeze vs your opponent and zone them properly then the wave will iterally never move.
