Represents an endless cycle of doing something; 'if one starts doing something, it will not stop'
Long explanation:
The たらきりがない grammar point is used to express an endless or cyclical action, often implying that once the action starts, it won't stop or end. The action is usually undesirable or negative, and the speaker implies that it should be avoided to prevent the cycle from continuing. This structure is mostly used after a verb in the た-form followed by きりがない.
