Morphology
knee + slapper
The compound literally links 'knee' with 'slapper' (one who/that slaps), so a learner who knows 'knee' and 'slap' can plausibly infer it refers to something that makes people slap their knees. However, understanding that knee-slapping is a culturally recognised laughter gesture (and that '-er' here denotes the cause rather than a literal person) requires pragmatic/cultural knowledge, so the relation is only partly predictable.
Etymology
The phrase knee slapper may come from the picture of someone laughing so hard that they slap their knee. That's why a 'knee slapper' means a joke that makes people laugh loudly.
