In Scandinavia, this word has several meanings: "bæsj" (baesj) means pooh in Norwegian; and "bärs" means strong beer in Swedish (originated from the Bayern district in Germany). Should not be confused with the Swedish word "bajs", which means pooh like in the Norwegian "bæsj".
In English the similar "bash" can refer to hitting fiercely, trying out something, or throwing a party.
Ska vi klämma en bärs? (Swedish, meaning "Let's squeeze a can of beer")
