Pattern
noun
様 uses its alternative meaning "manner" here, so we have an imitation manner. An imitation of the same manner over and over creates a pattern.
This is a jukugo word, which usually means on'yomi readings from the kanji. Since you didn't learn the on'yomi for 様 with the kanji, here's a mnemonic to help you out. You see a pattern in your yogurt (よう). The yogurt is an imitation of life. So deep, man. So deep.
