花札で、最初の手札に三組のペアができたら「くっつき」と言います。
In hanafuda, if you have three pairs in your initial hand, it's called 'kuttsuki'.
手役 is a broader term for any scoring combination in the initial hand, while 喰付き specifically refers to the three-pair combination.
The term likely derives from くっつく (to stick together), referring to cards that form pairs. The kanji 喰 is ateji, possibly chosen for its meaning of 'eating' or 'biting', suggesting cards that match or 'stick' to each other.
