'sblood

Etymology
Shortened form of God's blood. Primarily in the Middle Ages and up to the early modern era and to a rare extent today, people would curse on God/Christ's body parts rather than breaking the second commandment (not to use the Lord's name in vain oaths). In this case, the exclamation refers to Christ's blood shed during the crucifixion and the Eucharist under the form of wine.
