Her song is commentary on the irish language and how its taught in school. The langauge is taught in a very boring and forced fashion and peoples knowledge of irish fades rapidly in the years after school as ireland is English-speaking. So shes saying "i cant remember what to say" and "i dont speak irish anymore" or little joke lines she remembers from her irish studies like "may i please use the bathroom" or "suddenly" with no follow up. Its very clever.
