first base

First base can mean:

• First baseman in baseball.
• Slang for kissing, particularly French kissing. Often synonymous with "making out." See Baseball metaphors for sex.
• First Base, a German eurodance group.
• First Base, the 1973 debut album by English rock band, Babe Ruth.

First base, or 1B, is the first of four stations on a baseball diamond which must be touched in succession by a baserunner in order to score a run for that player's team. A first baseman is the player on the team playing defense who fields the area nearest first base, and is responsible for the majority of plays made at that base.
