Making-out while drunk is still cheating right?

If they got drunk and only made-out with someone else, is still cheating right?

Note: They didn't do anything else. There was NO sex. The person that cheated felt bad after the kiss, left afterwards and got taken home by a relative.

When people cheat, sex is involved most of the times. What if it only involved a drunken kiss?
