"Honestly, I was like my..." ??? I guess I'd need to watch the whole video for context. The guy is commenting on the prank.
The second part is a dialogue, so it's better to look at it fully. The first guy says the "Christmassy merch(andise) has now been dropped" (=made available). Then...
"I once almost got dropped." (Maybe he's referring to a girlfriend dropping him, ie. ending the relationship.)
"On your head as a baby?" (=a childhood accident which explains your stupidity now)
"...and that." :)
