The process of kissing over a long period of time in a comfortable place with someone special. It is different than making out because lips don't lock at any point, they only temporarily touch for a brief moment only to touch again after another brief moment. Tongue is used only to lick each others face or to have tongue wars.
"I love to spend long days with my girlfriendAlexa smooching out in her bed"
girlsgoing out with you on a friends-only basis (or in the context of 'hanging out').
is appropriate for a first date. not so for later dates.
my friend set me up for a night of mooching without smooching with his cute sister. first night was great, but now it's starting to feel like free beers for her and blue balls for me!
