A hug that is almost a hug, but climaxes as a cluster-fuck of random arm and body movement involving the two people.
Guy 1- Dude, Steve just saw his ex-girlfriend Guy 2- Oh snap! I thought he said she wasn't mad at him anymore
Guy 1- She's not, she approached him
Guy 2- Did they hug?
Guy 1- No man, they AWKWARD hugged
Guy 2- Oh shit.
Getka'd is similar to the phrase "GOTCHA". It means that one person essentially trolls the other person so hard in 'real life' that all of their plans, past and future, implode in their face.
"I flew 2000 miles to see this jerk I thought I loved, but it turned out he just wanted to get it in! I got Getka'd!"
