“Lollipop hand” is slang for a hand with only one strong card and nothing else.
Explanation. A hand like A‑2 offsuit, where only the Ace counts, is called a lollipop—sweet but insubstantial. It’s rarely playable outside in-position with special dynamics. Recognizing lollipop hands aids discipline in folding weak Ace-high hands that may pitifully fade.
