That which arises from the contact of the senses with objects, which at first is like nectar, but in the result like poison — that pleasure is remembered as rājasic.

Rājasic pleasure: viṣaya-indriya-saṃyogāt — from the union of senses and objects. Agre amṛta-upamam — at first, nectar (immediate, gratifying).

Pariṇāme viṣam iva — in result, poison (attachment, suffering, consequences). It is worldly sensory pleasure, which binds and eventually hurts.
