I might sound a bit "No Fun Allowed" but I always saw those "But hole" and "thrust attack" comments in front of female NPCs being left by /r/gaming mouth-breathers.
Favorite one was in DS3. There's a place in the demon ruins where you get to a huge ladder, extremely reminiscent of the sequence in MGS3 where the theme song is played, so of course that immediately starts going through my head. On the ground in front of the ladder is the message "lizard soup", which is of course the closest someone could get to "snake eater". I thought that was pretty great.
In DS2 I found a message by the even longer Snake Eater ladder that said "Like a dream..."
There's a million great ones that I'm forgetting right now. The only one that comes to mind is when I found "You bastard ahead therefore try pure luck!" with the collapse emote in front of one of the later bosses. I don't quite agree with the sentiment but I got a kick out of it just the same.
