happ, happ noises, excite = i say this alot when i'm happy or excited about something

JNBDSJKDWB, sNJHBDWHD???, overall keysmashing = keysmashing is the way i express laughter, happiness and in some occasions even positive embarassment ( flustered ), the ones with "???" at the end of them express confusion but its still a positive emotion!!

oof, yike = i usually avoid saying these in serious conversations, but i use them when i don't know how to reply to them so sorry if it makes you uncomfortable
