Nerds making out and
canoodling in public may give you "the feeling."
If someone tells a story with too many graphic details in front of your boss or parent, you may get "the feeling".
If someone tells a corny joke or
anecdote, you may get "the feeling". Same goes for over romantic, nostaglic, or
schmaltzy sentiments.
If someone falls, farts, or makes a fool of themself and you are directly next to them, you may get "the feeling."
