큐스포츠 용어 사전(https://en.wikipedia.org/wiki/Glossary_of_cue_sports_terms)

에 의하면 큐로 수구를 두 번 건드리면(접촉하면) 다음과 같이 DOUBLE HIT 라 설명하고 있습니다.

DOUBLE KISS를 TWO KISS라고 하지 않는 것처럼

TWO TOUCH란 용어 대신 DOUBLE HIT 또는 DOUBLE TOUCH 가 바른 용어일 것입니다.

double hit
An illegal shot (foul) in which the cue stick's tip contacts the cue ball twice during a single stroke. Double hits often occur when a player shoots the cue ball when it is very close to an object ball or cushion, because it is difficult to move the cue stick away quickly enough after the cue ball rebounds from the cushion or object ball.


The player hits the cue ball more than once during a shot (a double hit)
