In idiomatic use, the initial stage in a process, series, or relationship, especially implying a beginning level of intimacy or achievement.

Dialectal Variation

British vs American Usage

Differences

The literal term is understood in the UK due to cultural exposure but is not part of native British sports. The idiom is far more common and deeply embedded in American English.

Connotations

In AmE, the idiom carries strong connotations of romantic/sexual progression (e.g., 'getting to first base' = kissing). In BrE, while understood, it may be perceived as an Americanism and used more broadly for any initial stage.

Frequency

High frequency in AmE, especially in informal and media contexts. Low-to-medium frequency in BrE, largely in contexts influenced by American media.
