Bases are loaded意思
"Bases are loaded" is a term used in baseball to describe a situation where there are runners on all three bases (first, second, and third) with no outs or with one or more outs. When the bases are loaded, the potential for multiple runs to score on a single play is high, making it an exciting and tense situation for both the batting team and the fielding team.
The phrase can also be used metaphorically in non-baseball contexts to indicate a situation where there is a lot at stake or where the potential for something significant to happen is high.
