What do you mean by interlocking fingers?

Ten fingers locked is like, ten fingers locked, boys who want to lock their fingers must want to feel your body temperature and interact with you intimately. This is also a way for boys to gain a sense of security, and a way for boys to express their possessiveness of the people they like.

It should be noted that interlocking fingers is only an intimate behavior between couples. Generally speaking, holding hands can be carried out between relatives and friends, but interlocking your fingers is definitely a move that very close people will do. If a man always likes to buckle your fingers, he must like you very much. In addition, boys are generally restrained when expressing their feelings, and generally do not buckle their fingers with others casually. The man who clasps your fingers in public must love you very much.
