From the same phrase family as 'i have', 'i would', 'i'd tap' etc.
Used when somebody is
particularly impressed by something, most frequently a person.
Literally means 'I have', but said in a German accent to give it that extra 'ooft!'.
"Did you see that cumslut
last night? I had her a few days ago... she walked past and
i was all like 'Ooft, I haff!'"
