Take any multiple-word word or phrase that generally has an adjective as part of it:

• ice cream
• green thumb
• rock candy
• egg yolk

And then pretend the adjective is a verb and conjugate it in the past tense:

• iced cream
• greened thumb
• rocked candy
• egged yolk

This is easily changed into the same format as the Dark Souls "Victory Achieved" message:

• cream iced
• thumb greened
• candy rocked
• yolk egged
