look up any word, like donkey punch:
 
1.
To attend a large gathering of people where mingling with strangers is encouraged (e.g., a party or bar) but converse only with the small handful of people one arrived with.
"Those parties are bullshit for meeting people. Everyone just shows up and semisocializes in their own little cliques."

"The guy throwing that party might be douchey, but let's go anyway. We can drink his booze and semisocialize."
