The phrase "got bed with" is grammatically incorrect and may be a result of a non-native speaker's attempt to convey a meaning. However, if we break down the sounds of each word in IPA phonetic transcription, we can better understand how they are pronounced. "Got" is pronounced as /ɡɒt/, while "bed" is pronounced as /bɛd/. "With" is pronounced as /wɪθ/. To properly express a physical encounter, one would use the phrase "got into bed with" instead.
