TeeTee 

Originally from 尊い (toutoi), meaning precious, valuable or priceless, it became Japanese internet slang "ていてい (or てぇてぇ)" roughly meaning someone else's actions are wholesome, or precious.

Popularised in the west by subtitled V-Tuber clips, where it was used typically during moments where the V-Tubers were acting affectionate to one another; this hard to translate word was often simply romanised. This resulted in several spellings, the most popular of which seems to be "TeeTee", whith other variant such as: tee-tee, tee tee, tei-tei, TT and te-te.

Check out this clip of OkaKoro being TeeTee.

teke teke 

A Yokai spirit of a woman (sometimes a man) who is missing their lower half, The name "Teke Teke" comes from the sound of their lower half dragging across the ground. Not seeming it as they walk on their hands or elbows, the Teke Teke is extremely fast. The way Teke Teke acts is by chopping a person in half just as them.

Person: I heard weird noises last night, like dragging noises
Person 2: Maybe it was a Teke Teke hunting for a lower half
